Manga / Domestic Girlfriend

Go To

Upset when his teacher, Hina, does not return his feelings, Natsuo loses his virginity to Rui, a girl he meets at a mixer party. She's the one who suggests it, simply wanting to know what sex is like, and does not want to start a relationship. Things get much more complicated when Natsuo's father gets married again, and his step-siblings turn out to be Hina and Rui.

Domestic Girlfriend is a shonen manga by Kei Sasuga, author of GE - Good Ending. Currently in circulation since 2014, it was given an animated adaptation as part of the 2019 Winter Anime lineup.


Domestic Girlfriend provides examples of:

  • A Date with Rosie Palms:
    • Natsuo accidenally sees Hina doing this, while muttering her ex-lover's name.
    • Momo innocently reveals that she "does it" almost every night.
    • Natsuo's two friends, while showing Rui around the various sports clubs, absentmindedly mutter to themselves "I'll definitely fap to club activities (specifically, the sweaty girls doing sports) tonight." Cue the shocked look on Rui and Natsuo's faces.
    • Serizawa gets depressed and puts on some romantic movies and does this after she's told she's not seductive.
  • Affectionate Gesture to the Head: Hina gives these to Natsuo on several occasions.
  • Age-Gap Algebra: Hina's 23, and Natsuo is only 17. By the criteria of "Half your age plus seven", he's a little young for Hina. It is one of the reasons why she is reserved about pursuing a relationship with him.
  • Advertisement:
  • Almost Kiss: Natsuo tries to kiss a passed out Hina during their first night together under the same roof, but is stopped when Rui walks in on them.
  • Attempted Rape: Alex forces himself on Rui when he gets drunk.
  • Bishōnen: Kiriya-sensei and Hagiwara Shuu.
  • Brother–Sister Incest: When Natsuo and Rui had sex the first time they met, they didn't know of their parents' relationship. And Natsuo had feelings for Hina even before that. Later on, Hina returns his feelings. And after they break up, Rui too.
  • Cannot Spit It Out: Subverted. Natsuo is very straightforward about his feelings with his love interest. Most of the girls are the same, except for Miu.
    • Inverted with Rui in chapter 85. She straight-out tells Natsuo that she's taking the initiative.
    • Played straight with Serizawa who is always afraid to tell Natsuo her true feelings. And when she does she backtracks by saying she just got caught up in the moment.
    • Subverted with Hina after she comes back from exile. She actually did, but she was drunk and can't remember doing it. Played straight afterwards.
  • Casanova Wannabe: Alex. He claims to be "very popular with girls," but cannot even work up the courage to confess to Rui. It is revealed that in his hometown, he became disliked due to him unknowingly getting himself drunk from chocolate and kissing a girl in front of everybody at the party.
  • Clingy Jealous Girl: Rui, but very subtly.
  • Cosplay Café: During the school festival, the Literature Club organizes a Maid Cafe, with Rui, Momo, Miu and Alex dressing themselves as maids.
  • Death Glare: Rui is quite good at using this. In chapter 9, she (along with Natsuo) gives one to Shuu. She occasionally glares at Natsuo when he seems to be intimate with another girl. But the best one must be in chapter 2, when she catches Natsuo trying to kiss a sleeping Hina.
  • Defrosting Ice Queen: Rui starts off the series as fairly cold and anti-social, but begins warming up and gaining friends the more she hangs out with Natsuo.
  • Driven to Suicide: Natsuo and friends fear this is true for Yuka and race to prevent it. Fortunately averted.
  • Easily Forgiven: Alex is almost immediately forgiven for attempting to rape Rui. Granted he was drunk and he was stopped, and really regretted his actions afterwards.
  • Embarrassing Damp Sheets: In Chapter 79, there's an unusual case with Natsuo - one of his wet dreams results not in Nocturnal Emission, but in a nosebleed so severe he has to wash his shirt and pillowcase in secret. Rui notices him sneaking into the bathroom and follows, first making a quip about him having a period, then wondering just what he was dreaming about to get a nosebleed that huge. It was her.
  • Entitled to Have You: Kengo Tanabe, the man Hina's mother set her up with. He starts stalking Hina, repeatedly giving her gifts even after she returns them, and accosts her at work. When he is banned from her workplace, he hires a number of people to call over and over to harass her. This is all out of some insane attempt to "prove" that she needs him.
  • Fan Disservice: Alex in a maid outfit.
  • Fanservice: Panty Shot, French Maid Outfit, Hot Springs Episode, etc. And the (rather tastefully and hilariously done) Furo Scene. Additionally, some very steamy omake in the original magazine.
  • Faux Affably Evil: The man who Hina's mother sets her up with is polite, friendly, and always smiling, but also subtly controlling and manipulative. When things don't go his way, the "subtle" part goes out the window, and he bluntly tells Hina that he's spent enough time and money on her that she's basically already agreed to marry him. While still smiling pleasantly.
  • Feminine Women Can Cook: Rui and Momo are quite good at cooking. Hina also tries cooking by herself, with mixed results. In fact for Rui, it is this trait that Rui decided that she would pursue a path of Italian cooking, inspired by her biological father.
  • Food Slap: Shuu, the married man Hina was having an affair with, gets a glass of water thrown in his face after his first meeting with Natsuo and Rui.
  • Genre Shift: The story starts out as a Sibling Triangle. After Natsuo and Rui start dating (after Natsuo and Hina break up) that part is sidelined, and it becomes mostly a Slice of Life story.
  • Gratuitous English: It isn't obvious in fan translations, but Alex's dialogue is sometimes peppered with English words, especially when he's excited.
  • Gray Rain of Depression: After Rui finds out about Natsuo and Hina's relationship, she runs away in the rain.
  • History Repeats:
    • See Teacher/Student Romance entry.
    • When Kusumoto Saki offered to give herself to Kiriya-sensei, he was shocked, abruptly rejected her advances and avoided seeing her after that. This caused the girl to feel humiliated and make several ill-advised decisions. Later, when Momo does the same to Natsuo, he is much more level-headed, figures out the causes behind her actions and helps her deal with her problems.
    • When her love is unrequited, Kusumoto Saki began resenting Kiriya sensei, and sabotaged his job. Rui briefly tries to "hate" Natsuo when he does not reciprocate her feelings, but later decides against it and to treasure the moments they have together instead.
  • Hotter and Sexier: From the author previous work GE - Good Ending note . Here, like the premise says, it took only one chapter for Natsuo and Rui to have sex with each other, and most of the color pages leaned towards sexuality.
  • Incest Subtext: Natsuo/Hina/Rui normally don't count, since they all knew each other before they became step-siblings, but Natsuo does get very hot and bothered when Rui calls him onii-chan. Leo, on the other hand, is clearly in love with his sister Mao, and still sleeps in the same bed as her.
  • Identity Impersonator: Rui tries impersonating Hina to break up with Shuu. However, when Shuu answers the phone, her inability to string together a sentence quickly torpedoes that plot.
  • Important Haircut: Happens a few times.
    • Hina cuts it when she's forced to break up with Natsuo and then grows it back when she makes the decision to move back home and try to get back together with him.
    • Rui grows her hair out after Hina leaves because she thinks Natsuo prefers longer hair and cuts it again after she returns and Natsuo remains loyal to herself rather than get back together with Hina.
    • Miyabi cuts it after she finally works up the courage to tell Natsuo she loves him, only to get rejected.
  • Intimate Healing: By Natsuo to Rui. When she had a high fever (nearly 40 degrees Celsius), no one else was at home and the only fever medicine available in the house was suppositories (meaning it is to be inserted into the rectum). Cue a lot of blushing and sweating before he manages to get it done.
  • I Never Said It Was Poison: Used by Momo to get Kusumoto Saki to admit she was the one who sabotaged the Literature Club room.
  • Instant Sedation: Liquor has this effect on Natsuo.
  • Introduction by Hookup: The inciting event of the entire series is when Natsuo loses his virginity to Rui.
  • Kissing Under the Influence: Done by Alex to Natsuo and then to Kiriya-sensei. It is revealed in the flashback that this is also how he lost his first -and only- girlfriend.
  • Love Triangle: Between Natsuo, Rui and Hina.
  • Male Gaze: When Natsuo's friend offer to show Rui around the school's clubs, they pick the sports clubs first to ogle the girls being sweaty and/or clad in skintight swimming suits.
  • Messy Hair: Natsuo has a ridiculously ruffled bedhead when he doesn't sleep well. Later on, it happens to Rui as well.
  • Mood Whiplash: Chapter 53, as Natsuo is being upset with Hina's worry about their age difference, he is treated to the sight of Rui's thong-clad butt as she slips and falls over. Blood gushes out of his nose and Natsuo thinks to himself "This emotional jumping around will be the death of me!".
  • My Sister Is Off-Limits!: Mao's brother Leo is extremely protective of her, which is why she's still single despite being a shameless flirt.
  • Never My Fault: When Natsuo goes to visit Kengo Tanabe in prison, Tanabe thinks his trial is a formality and he'll be out soon. After all, he didn't mean to hurt anyone, it was Natsuo's own fault for jumping on the knife.
  • Nipple and Dimed: while the first few chapters did show Rui's nipples, by the time Natsuo and Hina start dating the manga begins to offer fully uncovered views of multiple characters breasts without even a hint of nipples or areola.
  • No Social Skills: Rui at the start of the manga. She starts to get better with the help of Natsuo.
  • Nosebleed: Natsuo suffers from this quite often, considering how many hot women he typically hangs around with.
  • Not Blood Siblings: Natsuo to Hina and Rui.
  • Not What It Looks Like: Natsuo sees Miu trying to takes a speck of dust off Kiriya-sensei's eye, and mistakenly thinks they are kissing.
  • Out of Focus: All of Natsuo's non-related high school friends when he moves onto college.
  • Painting the Medium: The segments taking place in America have all the word bubbles horizontal and placed as they would be in western comics, which contrasts heavily with the standard vertical bubbles in Japanese segments.
  • Panty Thief: In the chapter in which Alex is introduced, he helps Natsuo catch one of these.
  • Porn Stash: Natsuo calls them old-fashioned, since the internet exists. Fumiya does have a physical collection, however, and asks Natsuo to hang onto it while his cousins are around. Natsuo reluctantly agrees, ends up roping most of his friends into helping, and when that fails burns them in order to keep Rui from finding them. He misses one magazine that features busty older women. Hina finds it and assumes he still has feelings for her.
  • Pretty Freeloaders: Deconstructed: Natsuo takes in a young woman he met at a mixer who has nowhere else to go. She ends up being a drug runner and both of them end up kidnapped by gangsters and nearly killed after they catch her stealing some of the supply for her own personal use.
  • Reality Ensues: When a rich man starts stalking Hina, she has no idea what to do, and she keeps getting more and more depressed as she feels cornered. Then her coworkers convince her to call the police, they believe her, and they give the stalker a formal warning. When he attacks her later, he is caught and sent to prison. Hina lampshades that she should have just called the cops in the first place.
  • Really Gets Around: Momo. Before meeting Natsuo, she dated at least thirty guys one after another (and it's implied that she slept with quite a few). This is primarily due to her loneliness, which Natsuo helps her overcome.
  • Right Through the Wall: Downplayed; even with a gag in Rui's mouth, Rui and Natsuo are loud enough that their father hears. Thankfully, he just assumes Natsuo was watching porn.
  • Sex as a Rite-of-Passage: The series starts with Natsuo and Rui having sex just for the experience of it. They quickly realize it hasn't actually made them any more mature. In fact, most of the least mature people in the series are the most sexually experienced.
  • Shout-Out: In chapter 53, Natsuo tells Alex that his argument with Rui was about whether eggs should be eaten with soy sauce or salt (an argument that happened between two people who were dating).
  • Sibling Triangle: Hina and Rui for Natsuo. To make things more complicated, they become his step-siblings.
  • Strong Family Resemblance: Hina and Rui look very similar, except for hair length and chest size. Natsuo notices it when he first meets Rui, but assumes he's just projecting his feelings for Hina onto her and doesn't make the connection. Much later, it becomes clear that both girls take after their father in appearance.
  • Teacher/Student Romance:
    • In Kiriya-sensei's backstory, Kusumoto Saki had an unrequited crush on him. It didn't end well.
    • Hina had a crush on Shuu when he was a teacher at her high school. However, they didn't start dating until she graduated from university.
    • Natsuo wants one with his teacher/step-sister Hina. They do eventually get together.
  • Unwanted Harem: Unfortunately for the girls, Natsuo only has eyes for Hina. And then gradually toward Rui instead, after Shuu lies to Natsuo by saying Hina's completely moved on from him.
  • Your Cheating Heart: The man Hina was dating, Shuu, was married to another woman. This upsets both Rui and Natsuo when they find out, and they later make it a mission to break them up.
  • What the Hell, Hero?:
    • Natsuo and Rui call Hina out for having an affair with a married man named Shuu. They try to convince her to break it up, but she ends up silencing both of their arguments. She changes her mind after the two's first meeting with Shuu, and how he was a bit condescending towards them in addition to constantly stringing her feelings along.
    • Natsuo is subjected to this when Rui finds him at Hina's apartment, after he lied again about being at Fumiya's place. The tears in her eyes and the reaction in her face says more than words could during this moment.
    • Natsuo gives an epic rant to Hina after she endangers herself and her family by not telling them that she has a stalker.
  • Write What You Know: In-universe, all of Natsuo's stories are based on things that have happened to the people around him. Experienced authors suggest he interview interesting people to expand his knowledge base. When Rui notes he hasn't written a story about her, he jokes that it will be erotica. After they start dating, he does write an erotic story about her, with her permission.
