As the sun rises, Yoichi keeps sleeping. Hana tries to wake him up and he starts screaming but soon calms down when she teasingly tells him he is already late. If he doesn’t get up soon, she’s going to play a prank on him.
He wishes her good morning, addressing her as "ma’am," but she reminds him that he calls her "mom" at home and shares that breakfast is ready. Hana pinches his ear and insists he call her "mother" or else he will miss out on his meal. Hana is obviously not his mother, and she teasingly tells him to keep the tough persona only for his personality.
He gets embarrassed, and she tells him to calm down before coming for breakfast while laughing. Yoichi is staying overnight at someone’s house who isn’t even his real mother. During the spring of his first year at university—or more precisely, 24 hours ago—everything in his house burned down.
The cause appears to be sparks from the refrigerator’s compressor falling on some scum left by a resident on the floor. The boy became homeless right after his first month at university. With nowhere to go, he decides to call his university friend for help, admitting that he doesn’t have any other friends.
The friend tells Yoichi that he will eventually have a girlfriend and doesn’t want another guy staying at his place. However, his parents’ house is available, though it’s a bit far from the university; it’s in the same prefecture, and Yoichi can stay there for a while. Itsuki tells him the house is big and that he will contact his family.
The boy texts for help and arrives at the address given by Itsuki. The boy notices that the house is far back in the countryside. He never thought the scenery would change so much from his previous apartment, which was just three stations away.
In front of the house is the Pacific Ocean, and he worries that if he can’t find a place after coming all the way here, it will be a problem. As he approaches the house, he is greeted by a lady with a large chest. She teasingly says, “Welcome back, honey,” which makes him embarrassed, and he tells her she might be mistaken.
She starts laughing, realizing she has piqued his interest. Hana explains she was just trying to act like someone in a guest house. She gets close to him and asks if he wants food, a bath first, or if he wants her.
The boy is confused and notices that she is a tanned beauty and seems young. He asks if she works part-time, and she shares that she has heard about him. The boy introduces himself and expresses his gratitude for the accommodation despite his specific request.
Hana welcomes him once again and asks if he has any injuries since his house burned down. The boy has only a burn on his face. Hana mentions that since it’s a guest house with many rooms but few customers these days, he can take a room and stay there for a while.
Hana tells him she is the landlady, but the boy remembers that his friend’s mother was the landlady. He is a bit confused, but she clarifies that she is both the mother and the young landlady, which shocks him. She explains that she doesn’t have any children and that his friend’s parents are not there, so she is the auntie taking care of Itsuki.
The boy gets a call from his mother, and Hana says he is not picking it up. He shows her that it’s fine. She shows him the room and tells him he will be staying here from today onwards.
She shares a bit of history about the guest house, which opened in 1980 but is still very neat. Hana provides information on using the TV and refrigerator and asks him to make sure not to make any noise after 9:00 p. m.
The boy questions if all guest houses are like this, while Hana tells him that meals start at 6:00 p. m. , and he can take a bath afterward if he likes.
Before leaving, she tells him that he can relax in the empty room. As soon as Hana leaves, his phone starts to ring, and he answers the call. Itsuki asks if he was able to reach the place, and the boy angrily tells him that Itsuki should have informed him beforehand that his house was a guest house.
His friend thinks the boy would have rejected the idea if he had said something before, and the boy apologizes for the misunderstanding, promising that he will definitely pay him back someday. Itsuki remembers that the boy likes girls who are kind to otakus. The boy gets angry, questioning why his friend is bringing that up now.
Itsuki says it would be great if something like that actually existed, but acknowledges that such things are only fiction. Itsuki reads what the boy wrote in his diary. The boy went to Namaji Predatory School and admires real girls.
No girls have ever talked to him, but if there was a kind female, he could close the distance in a friendly way, and if things go well, he could take advantage of her low sense of charity and have her do something naughty to him. Itsuki recalls that his friend only purchases content that satisfies such delusions and saves them on his phone. The boy is shocked and questions how his friend accessed his phone.
Itsuki wonders if the boy could actually spend time with such a woman in the guest house and sends him a picture of her. Itsuki gives the boy time to think about his decision, but the boy is still confused as he looks at the picture. He sees the beautiful girl in the picture and calls her cute.
Yoichi reads the message about the stunning girl being in the guesthouse and suddenly starts running outside to ask Hana about her. However, when he arrives, he sees her in a strange position, realizing he came at a bad time. Hana asks if he wanted to take a bath first and mentions she is a bit lazy, so she takes her time cleaning, but he can still get in if he doesn’t mind.
Yoichi says he can take a bath later but wants to at least help her. He is eager to ask about the girl staying at the guesthouse but decides to first express his gratitude for allowing him to stay there. He looks at her and thinks that he was never aware of someone older than him in this way, but since she is his friend’s aunt, he feels a bit hesitant.
He gazes at the beautiful young lady, and after a while, she shares the spring seafood dishes while offering him liquor. Hana notices he is a bit hesitant and asks if he doesn’t want liquor. The boy questions if she drinks in front of other customers as well.
Yoichi tells her that she prepared such a delicious meal for him, but he doesn’t have much money right now. Since his friend didn’t mention it was a guesthouse, he is unsure if he can pay for the accommodation. She reassures him not to worry, saying she just wants to take care of Itsuki’s friend, as he rarely invites anyone.
He expresses his gratitude and notices that the sashimi looks as beautiful as jewels. The boy questions if she was the one who cooked such delicious meals, thinking that this food is luxurious for a poor university student. Hana is happy to see that he likes the food.
While staring at her, the boy realizes he feels at ease with her. As he gazes at her chest, he thinks she makes his heart flutter. Suddenly, his phone starts ringing.
He uses the excuse of eating to avoid answering, but Hana picks up the call instead. She tells Yoichi’s mother that she is Itsuki’s mom. Hana explains that after hearing what happened, she took him in, and the boy couldn’t answer the call because he was occupied, so she decided to pick it up for him.
They continue chatting while Yoichi is left speechless. He doesn’t understand what they are talking about, but while Hana happily hands his phone back, he feels that she really connected with his mother. Hana says his mother was worried, but he tells her he just felt awkward and questions if Hana will now call him out for not getting along with his parents properly.
Hana understands, saying that she is not Itsuki’s real mother either. Although the university is a bit far, she says he can still live there without going out of his way to live alone. Yoichi shares that his parents are good and loving, but their expectations were too much for him.
When he went to high school, he couldn’t keep up with his studies and felt guilty for not meeting their expectations. Because of this, he couldn’t get accepted into the university of his choice and decided to go to a university in the countryside. However, on the very first day, his house burned down, which makes him laugh.
He knows his parents will definitely try to support him after what he went through, but he honestly doesn’t want to be a burden on them anymore. Hana suddenly grabs his face and hugs him. She explains that guesthouses are originally private houses; they are not as spacious or luxurious as inns and usually have casual decorations.
She always wears casual clothes like an apron, and the bath doesn’t have a splash either, so the place is a bit inferior compared to an inn. But that's the nice part—it feels like a safe home. Whenever someone feels anxious at work or traveling, they will be happy to have a place like this to return to.
Hana says she is both the landlady and a mother for such people. She wants to be that kind of person, so if he doesn’t have a place to stay, he can call this place his home. He can call her his mother, and if he is too embarrassed, he can use her name, Hana, without any honorifics.
With his face buried in her chest, he decides to call her Hana instead. She tells him the guesthouse will warm him in many ways. After they are finished, he thanks her for the meal and says it was delicious.
She is happy to see that he is satisfied. Yoichi asks if there is anyone else apart from her. Hana informs him that it's a family business consisting of three people, including herself and her parents.
He shows her a picture and shares that he heard she was staying at the guesthouse. Upon seeing the picture, she becomes speechless and asks where he got the photo. The boy tells her that Itsuki sent it to him and mentioned she was at the guesthouse.
He embarrassingly assures her there’s no deep meaning behind why he is asking; he was just curious if such a cute girl really existed. Hearing this, she starts blushing and asks if these are the type of girls he likes. She assumes he likes flashy girls with tongue piercings and that he probably thinks she has a low sense of chastity and will do naughty things to him.
Hana lies, saying that the girl in the picture is her niece, who is still in high school and only helps out during long vacations, so she isn’t here right now. Yoichi believes her and realizes this is why they both look very similar. She mentions that she’s not the one he thought, and acknowledges that it must be boring for him to live in the countryside with no young people.
However, until he finds his next place to stay, he can take it easy. As she is about to leave, Yoichi calls his friend a liar and assumes the girl in the picture is probably his younger sister or cousin. Hana hides the truth about being the girl with the pierced tongue and slides the door shut.
Yoichi looks at a picture of a couple and comments how jealous he is, realizing there's no way someone like him could get a girlfriend. Hana sneaks up from behind and jokes that if a university student starts living alone, they'll definitely get a girlfriend. Startled, he admits he doesn’t even have a room.
With a wicked smile, Hana teases him about what couples do these days. He insists she’s wrong, and she responds that she only studied until high school, took over this place, and raised Itsuki. Yoichi remembers he has classes in the afternoon but doesn’t feel like going.
Hana invites him to the sea, and he recalls how, just a month after starting university, his house burned down. Now, he’s far from being alone with a girl, living in a guest house, and feels like he’s lost his chance at love. He acknowledges she’s his friend's aunt but thinks she's being too casual around him.
From the moment they met, she's been pushy, and he assumes she's played around a lot. Then he notices her in a red suit. Hana gets ready to fetch some ingredients, mentioning she’s a member of the local fishing union, has a proper permit, and usually gathers seafood for the guest house herself.
Yoichi realizes her sunburn must be from this and feels disappointed it’s not a swimsuit event with the landlady. She heads into the water and soon emerges with seafood. Since Yoichi is from the city, she guesses he’s never eaten something he's caught himself, so she prepares a piece for him.
He finds it delicious, and Hana is glad he’s feeling better. She tells him he can go to university if he’s feeling fine now and reminds him to be back by 9:00 p. m.
Surprised by her kindness, Yoichi reflects on it after class. He can't meet Itsuki today, but a female classmate invites him to a small gathering. Realizing it’s a good chance to expand his social circle and meet girls, he hesitates because he needs to be back by 9:00 p.
m. Despite it being his first gathering, Yoichi prioritizes the guest house rules and politely tells her he needs to leave early. At dinner, Hana notices something’s off and asks if the food tastes bad.
He reassures her it's not that; he’s just disappointed about missing his chance to make friends. To cheer him up, she says they’ll be free after 9:30 p. m.
, and she’ll keep him company. Later, people at the guest house start drinking, and Yoichi notices Hana has changed into casual clothes after work. They head to a bar, where some girls and customers warmly greet Hana, but she declines their invitation.
Yoichi observes how popular she is. The bartender says she’s seen Yoichi somewhere before, but Hana thinks she’s joking. She orders two highballs, but the bartender refuses to serve Yoichi alcohol and gives him tea instead.
Hana asks why Yoichi was worried earlier and offers to give advice or suggests asking her friend Ren, the bartender. Yoichi is surprised to see Ren is young and cheerful despite her tough appearance. Hana assures him Ren knows a lot about couples, and Ren shares that important traits like kindness and compassion are key to future relationships.
Hana teases Yoichi about why he’s not sitting closer, and he apologizes, saying the chairs are too close and their bodies might touch. Hana then asks what he thinks is the most important element in love. He shyly says "maybe looks," which makes her laugh, calling it the answer of a virgin.
Ren jokes that he’s not cut out for love. Other customers chime in with their opinions, but Yoichi disagrees with them. Hana agrees that looks might matter at first, which is why he’s interested in the girl from the photo.
Embarrassed, Yoichi listens as Hana wonders if her son has a girlfriend. She admits she doesn’t know much about Itsuki’s life since she’s not his real parent. Yoichi, feeling comfortable, says he could share everything with her since he’s a good friend of Itsuki.
But he's still confused about kindness and compassion. Hana suddenly moves closer, teasing him and revealing her chest. Yoichi, flustered, notices a mole and the gap in her bra.
Hana laughs at his red face, calling him cute. Other customers agree it’s a bit much, saying they’re also getting red. Still laughing, Hana explains she just wanted to have some fun since she noticed Yoichi was always looking at her.
She advises him to focus on a girl’s eyes, not her chest, if he really wants a girlfriend. Yoichi, embarrassed, thinks she must hate him now. Ren reassures him, saying it’s rare to have such a nice woman looking after him, and he’s luckier than most university students.
Listening to her, Yoichi starts admiring how cute Hana looks while chatting with the other customers. Yoichi stares at the photo Itsuki sent, and a sudden realization hits him: the mole on the girl in the picture matches the landlady's. His heart races as he wonders if Hana, the landlady, has been hiding something or if it's all just a coincidence.
He recalls how his life has drastically changed ever since he moved to the guest house. The thought of how Hana makes his heart pound every day crosses his mind, but his logic quickly steps in, reminding him that he's just a guest and should stay respectful. He’s tempted to relieve some of his pent-up frustration but decides against it, fearing that Hana might somehow find out.
The next morning, Hana, ever observant, playfully assures him that it’s perfectly fine and that at least he’s healthy. Embarrassed, Yoichi remembers his first wet dream from the previous night and how Hana caught him while he was trying to wash his briefs. Despite his awkwardness, Hana brushes off his concerns, telling him she’s used to these things and will handle the laundry herself.
Her nonchalant attitude leaves Yoichi both flustered and confused, as his curiosity about her deepens. Hana advises Yoichi to buy some new clothes since he’s skipped classes and only has one set. As he heads out, his thoughts drift back to how much she resembles the girl in the picture.
He calls his mom to assure her he’s fine and has everything under control, including new clothes and his plans for university. But Yoichi knows he needs to start looking for a new place soon. After all, he doesn’t want to overstay his welcome, especially after the wet dream incident, and he’s unsure how to deal with his growing attraction to Hana.
When he returns to the guest house, he sees new guests arriving, including a newlywed couple. Hana, ever the charismatic host, pulls Yoichi into the conversation, joking that they’re a newlywed couple running the guest house together. He quickly tries to correct her, but she waves it off with a playful laugh, turning her attention back to the guests.
Watching her effortlessly interact with the customers, Yoichi can’t help but admire her ability to connect with people so naturally. During dinner, the newlyweds rave about the lavish food, while Hana chats with them casually. When she notices the girl’s ring, the newlywed bride mentions how she made her husband buy her an expensive one and always takes care of it.
Hana comments that women often cherish the things given by their loved ones for life, a remark that sticks with Yoichi as he quietly listens. After his bath, Yoichi finds himself thinking about Hana again and how remarkable she is. Just then, he hears noises coming from the other room.
It's clear what the newlywed couple is up to, and it embarrasses him. Hana enters the room unexpectedly, startling him. She brings in his freshly laundered clothes and, with a mischievous smile, teases him about the noise, saying couples who stay at the guest house often find themselves in the mood for intimacy, and the place has earned a reputation as "the house of children.
" She laughs, then asks what he was going to request of her earlier. Feeling flustered, Yoichi blurts out an awkward request: he asks to see her tongue. He explains that he wants to confirm if she’s the same girl from the picture, feeling embarrassed as the words leave his mouth.
Surprisingly, Hana complies. She opens her mouth, revealing her long, pierced tongue. Yoichi stares, completely mesmerized by how sexy it looks, and starts to blush.
Hana, noticing his reaction, tries to say something with her tongue still out, which only adds to the awkwardness. Before leaving the room, Hana gives him one last playful comment, telling him not to take too long if he really wants to do "it. " As she walks away, Yoichi is left with his thoughts in a whirlwind.
In the bathroom, Hana removes her piercing, feeling a bit foolish. Meanwhile, Yoichi realizes that Hana is indeed the girl in the picture, but instead of feeling relieved, he's even more confused. He knows he has to move out soon or risk falling in love with her—something that could complicate everything.
Hana playfully asks if he enjoyed his stay last night, and he realizes she found out because of his scent. He remembers how last night, he could only think about Hana. She mentions that the couple from yesterday has been flirting all morning and had four rounds the previous night.
Teasing him, she brings up the scene from yesterday, leaving him wondering if this is the difference between an adult and a virgin. Realizing he needs to find a new place before he falls for her, she offers a suggestion, saying he can stay at the guest house if he ever finds a girlfriend, and that she’ll show the same hospitality. Seeing her playful tongue again makes him flustered.
Later, as the couple leaves, Hana jokingly tells the wife to kiss her husband more often. Yoichi then questions what kind of mother Hana must have had. Suddenly, someone behind them tells Hana not to speak to the customers in such a way.
He turns around and realizes it’s the other landlady—Hana's mother. He quickly connects the dots, remembering that she’s his friend’s grandmother. If Hana’s grandmother is 35, that means her mother must be over 50.
Hana’s mother lectures her about acting childish, and Hana apologizes. While observing the exchange, Yoichi is taken aback by how intimidating the second landlady appears. When Hana’s mother calls him over, Yoichi wonders if he’s about to be lectured as well.
To his surprise, she thanks him for taking care of her daughter and grandson, leaving him speechless. Noticing that he doesn’t seem well, she asks if he’s been sleeping enough and offers some advice. He’s impressed by her hospitality, but Hana awkwardly tries to get her mother to go rest, mentioning her night shift.
Her mother insists that she doesn't need to, as it's Saturday and they're fully booked. Hana argues she can handle it herself, but her mother points out that Hana has barely been keeping up with her work and hasn't even finished her diving certification, which might inconvenience the customers. While watching this, Yoichi realizes it’s the first time he's seen Hana in such a vulnerable state.
He offers to help, saying he has no problem cleaning the bathroom since he’s done it before. Given that there are about five hours between check-out and the next check-in, the employees must clean all the rooms, bathrooms, and facilities. The second landlady explains that they also need to throw out the trash left by the customers and clean the sheets.
She decides to work alongside Yoichi. As they clean the futons, he resolves to do his best, finding himself surprised at how different the landlady’s mother is from what he had imagined. She is strict, calm, and gentle—very traditional and elegant.
The only similarity between her and Hana seems to be their genes. At one point, as he gazes at her chest, she tells him to keep his hands working. While cleaning, they come across a vibrator left in the futon.
The landlady's mother is clearly annoyed by it, calling it indecent. Items like this, left behind by customers, are kept for two weeks before they are discarded. Yoichi notices just how opposite Hana and her mother are.
When they finish, the landlady’s mother thanks him for his hard work, but he insists it was nothing. She mentions that Hana does all of this by herself every day, which shocks him. She also shares that her grandson used to help, but he left as soon as he could, which makes Yoichi angry.
He wonders if he was sent here just to cover for his friend’s responsibilities. The landlady’s mother goes on to explain that, after all this work, it’s impossible to cook, so her husband handles the meals, while Hana barely knows how to cook anything beyond Arajiru fish. Yoichi recalls his first day and realizes that Hana must have worked extra hard when he arrived, wanting him to enjoy the dish.
He’s puzzled by why the landlady would go to such lengths for him and eventually falls asleep. When he wakes up, he finds himself resting on both Hana and her mother’s laps, realizing he must have dozed off due to lack of sleep. Lying there, he thinks it’s a luxury, while overhearing them talk about him.
Hana’s mother praises him for working hard, being careful with everything, and not complaining. She thinks her grandson has made a great friend, but Hana teases, saying that while Yoichi may seem proper, he’s actually a complete horndog. She adds that he’s into gals, always sneaking glances at her cleavage, and even confessed he has a tongue fetish.
Her mother finds it all very indecent, leaving Yoichi to feel like all the points he earned have just vanished. Hana’s mother worries that Yoichi’s behavior might cause issues if he stays at the guest house and suggests that, since Hana is so busy, she herself will take care of him. She even offers to monitor his studies, as he’s a university student, and they don’t want him slacking off.
Yoichi starts to realize how different Hana’s mother is from her, but Hana brushes it off, saying her mother is just lonely since Itsuki left the guest house. She grabs Yoichi, declaring that she won’t let her mother have him. The senior landlady calls Hana modest, but Yoichi begins to understand that staying at this guest house might keep him from sleeping well, and if this keeps up, falling in love will be the least of his worries—he might just die from insomnia.
