    Kotoko Aihara 
https://static.tvtropes.org/pmwiki/pub/images/kotoko_aihara.jpg
Voiced by: Nana Mizuki
Portrayed by: Aiko Sato (1996 J-Drama), Ariel Lin (2005 Tw-Drama, 2007 Tw-Drama), Jung So-min (2010 K-Drama), Honoka Miki (2013 J-Drama, 2014 J-Drama), Sucharat Manaying (2015 Th-Drama), Reina Visa (2016 J-Movie), Esther Wu (2016 Tw-Drama)

An excitable, ditzy klutz with coppery hair. Has been in love with Naoki Irie since the first year of high school.


  • Adorkable: She's utterly ditzy, clumsy, but insanely cute. Her father sums it up very well when Naoki is proposing:
    Shigeo: "Naoki, my daughter can't do anything right."
    Naoki: "I know."
    Shigeo: "She's quite stupid."
    Naoki: "I know."
    Shigeo: "She can't cook."
    Naoki: "I know."
    Shigeo: "She's always messing up by jumping to conclusions."
    Naoki: "I know."
    Shigeo: "But she's cheerful, brave, driven, and cute!"
    Naoki: "I know."
  • Anguished Declaration of Love: Her repeated acknowledgment when Naoki says she will only ever love him despite just saying otherwise. Luckily for her, ensues an Anguished Declaration of Love from him.
  • Armor-Piercing Slap: She gives a hugely satisfying one to Naoki, when he flippantly recites the content of her Love Letter to him in front of their family.
  • Beautiful Dreamer: As Moto-chan notes, she really looks sweet when asleep. It's why Naoki kisses her when she falls asleep in the woods.
  • Betty and Veronica: The "Betty" (Book Dumb and relatively nice) to Yuuko's "Veronica" (Academic Athlete and cold) for Naoki's "Archie". In the end, Naoki chooses Kotoko.
  • Beware the Nice Ones: While Kotoko can get easily annoyed, she won't get angry. However, if she's pushed too far, she won't hold back. Just ask Naoki after she slapped him for flippantly reciting her Love Letter in a mocking fashion.
  • Big Damn Hero: Once saves Yuuki when he was about to drowning in a pool. Not that he openly thanked her.
  • Blithe Spirit: Pretty much so. She's cheerful, plucky and her ditziness doesn't stop her from make road to herself and change the rules when she wants to.
  • Book Dumb: Kotoko's scores placed her in Class F in high school. Despite working hard at studying, she just doesn't get it unless Naoki tutors her. Regardless, she eventually does achieve a Top 50 midterm in high school, get accepted into college, and then gets into and graduates nursing school.
  • Broken Pedestal: Played for Laughs with her mother. She died when she was very little, and Kotoko has been always shy about speaking of her because she remembers very little of her and has built an idealized image of a flawless woman. A wacky visit to her mother's original town proves that she was instead the spitting image of her daughter in both appearance and personality (clumsy, hopeless with cooking and studying, and very determined in her pursuing of her eventual husband), much to Kotoko's shock and Naoki's huge amusement. Kotoko's shock doesn't last since she now feels closer to her.
  • Brooding Boy, Gentle Girl: The sweet, encouraging Gentle Girl to Naoki's sullen, cranky Brooding Boy.
  • Can't Hold Her Liquor: Definitely not. She ends up being loud and blubbering nonsense at the worst time. Hilarious to watch, tough.
  • City Mouse: When visiting Naoki's family in Kyushu, Kotoko doesn't fit into their country life and is the Butt-Monkey for most of the episode.
  • Clingy Jealous Girl: Downplayed. While she acts this way, especially as a young adult, it's never too obsessive.
  • Cool Big Sister: To Konomi, whom she helped get close to Yuuki and bond on their shared personality traits.
  • Cry Cute: With that big brown eyes of hers and that Tender Tears, she's insanely cute when she cries.
  • Cry into Chest: She does to Naoki numerous times throughout the series.
  • Cute Clumsy Girl: Seen to fall or trip more often than not, fumble things constantly, and ends up relying on those around her because of it.
  • Determinator: Nothing would dissuade her from her goals (either her pursuit of Naoki or anything she puts on her mind). She never gives up.
  • Devoted to You: Very devoted to Naoki and played very straight.
  • The Ditz: Completely, even her own surroundings or what she's doing at times.
  • Dude Magnet: Just ask Irie, Kinnosuke, and Keita (her Nursing friend). In the manga she even got crowned Queen of the Tonan university by lot of guys.
  • Fairytale Wedding Dress: She gets to wear one. And boys, does she look beautiful.
  • Fiery Redhead: Downplayed. She's sweet most of the time, but she has also the Plucky Girl personality usually displayed by this trope, and when instigated (by Naoki most of the time) shows how fiery she can get.
  • First Love: Kotoko is Kinnosuke's first love. He doesn't get her. His Second Love, Christine Robbins, does. Also Word of God confirms she was Naoki's First Love.
  • Generation Xerox: She is the spitting image of her mother in both look and personality (clumsiness and cooking skills). Shigeo even tells his son-in-law Naoki that she pursued him by sitting everyday in the restaurant where he used to work until he grew fond of her. Naoki says amused that they're two of a kind indeed.
  • Genki Girl: Definitely so. At one point Naoki even tells her he actually envies her energy.
  • Girlish Pigtails: When she's not wearing her hair loose, she usually wears it in pigtails or braided. Or even wears Odango Hair.
  • Happily Married: To Naoki, plus Babies Ever After.
  • Hidden Depths: Despite being a ditz with lackluster intelligence, she's hard-working, has high perseverance, and deeply cares for others.
  • Hospital Hottie: Well, see it yourself. Not bad having her around, right?
  • The Jinx: Played for Laughs in the chapter where Naoki is going to take his entrance exam and Yuuki tells her to stay away from Naoki since where she's around nothing good happens to him. Turns out he was somewhat right, since everything Kotoko does with good intentions backfire with Naoki getting late at the exam or injured. He later tells her he's fine with it since he's never experienced difficulty or worry and she's making his life more interesting.
  • Kick the Son of a Bitch: When Naoki ridicules her and her feelings for him in front of their respective classes, she shows his Embarrassing Old Photo to everyone. His reaction is intensely satisfying.
    • The very first time she stands up to Naoki is when he's about to donate money for the rebuild of Kotoko's house after having rudely rejected her the day before and being the last person she would like to do it, and to get her and Kinnosuke out of his way since he's annoyed. Kotoko slams his money to his face and gives him a well-deserved "The Reason You Suck" Speech. Even the usually emotionless Irie looks astonished.
    • Also, when she's bullied by Naoki's little cousins while trying to help them with their homework, knowing she's a Book Dumb, she flatly refuses and airs their dark secrets that she has unknowingly learned from the ghost of their ancestor. The little brats instantly go away and help her with her household chores.
  • Last-Name Basis: She keeps calling Naoki "Irie-kun" even after living under the same roof for years and getting married. Ditto for Naoki, who keeps referring to her as Aihara until he eventually switches to her first name as a sign of growing affection.note 
  • Like Parent, Like Child: Her mother died long before anything shown, even flashbacks. She remembers very little of her, and has idealized her to be a flawless lady. A wacky visit to her mother's original town proves that she was instead the spitting image of her daughter in both appearance and personality (clumsy, hopeless with cooking and studying, and very determined in her pursuing of her eventual husband), much to Kotoko's shock and Naoki's huge amusement.
  • Living Emotional Crutch: To Naoki. He even confess he can be true to himself only when Kotoko is with him, and goes through a massive Heroic BSoD at the thought that she may leave with someone else.
  • Love at First Sight: She fell in love with Naoki when he pronounced the opening speech on their freshman year.
  • Love Confession: To Naoki. Over and over, again and again.
  • Love Letter: Her original way to tell Naoki her feelings. It was dismissed before even read. He eventually reads it when she was sleeping, naturally memorizes it, and flippantly recites it in front of the entire family and her father.
  • Love Martyr: Despite the fact that Naoki is kinda a jerk, she's never giving up him. He actually loves her just like she loves him, but has an hard time showing it.
  • Manic Pixie Dream Girl: Downplayed. She's the one who defrosts a little Naoki, but by changing completely his ways, but rather helping him finding his path and come to terms with his feelings.
  • Mistaken for Pregnant: In the first periods of her marriage, Kotoko is wrongly assumed to be pregnant. It was a false alarm but the experience made her and Naoki wish to have a baby.
  • Nice Girl: She's a sweet and friendly girl.
  • Oblivious to Love: She's oblivious to her coworker Keita's feelings until he says it out loud. And of course was totally unaware that Naoki has been loving her all along.
  • Older Than She Looks: She's small and slim-built, so she's often assumed to be younger. A foreigner mistakes her for an elementary student, while in the manga Naoki teases her for being flat-chested like she stopped growing up in primary school. Not that he doesn't like it anyway.
  • Plucky Girl: She's brave and optimistic. Even one of her best friends, Jinko, says Kotoko is her "pillar of hope for life".
  • She Cleans Up Nicely: Kotoko is already pretty but looks stunning when she's dolled up for her 20th birthday or the coming-of-age ceremony in the manga. Naoki even acknowledges this when says he qas upset about his mother organizing their marriage two weeks after their engagement but since she looks gorgeous on her wedding dress he doesn't care anymore.
  • Shipper on Deck: Tries to help any of her friends get with those they love. While she's generally mistaken (e.g. Tomoko for Keita), she does end up helping Chris and Kinnosuke get together. In the manga she's the one who pushes Konomi to Yuuki.
  • Single Girl Seeks Most Popular Guy: She doesn't like him because he's popular, but she is in love with and seeks Naoki, who's always the most popular guy.
  • Single-Target Sexuality: She's never taking the slightest interest in others guys beside Naoki.
  • Strong Family Resemblance: A photo showed that Kotoko inherited all' of her looks from her mother. In fact, when Naoki first sees her mother's photo, he thought she was Kotoko.
  • Tender Tears: She sheds these in the most emotional moments as a trait of her kindheartedness (and looking even more adorable).
  • They Just Don't Get It: Generally-speaking she doesn't get a lot of things, even when Naoki tutors her.
  • Wacky Parent, Serious Child: He's serious and stoic compared to his excitable mother.
  • What Does She See in Him?: Zigzagged. On the face of everything, Naoki's an ace genius and very handsome. Other than that he's often cold, brash, distant, and/or insensitive. So those who only know his basic qualities and do the opposite, while those who know his true personality play it straight and even talk to her this way.
  • You Keep Using That Word: Even after she and Naoki having been living under the same roof for years and eventually got married she keeps calling him Irie-kun, which strangers find a bit weird.

    Naoki Irie 
https://static.tvtropes.org/pmwiki/pub/images/irie_naoki_1.jpg
Voiced by: Daisuke Namikawa (drama CD), Daisuke Hirakawa (anime)
Portrayed by: Takashi Kashiwabara (1996 J-Drama), Joe Cheng (2005 Tw-Drama, 2007 Tw-Drama), Kim Hyun-joong (2010 K-Drama), Yuki Furukawa (2013 J-Drama, 2014 J-Drama), Pirath Nitipaisalkul (2015 Th-Drama), Kanta Sato (2016 J-Movie), Dino Lee (2016 Tw-Drama)

He's a tall genius with sandy brown hair, the oldest child of his family, and often blunt.


  • Academic Athlete: Naoki is not only a brain, but he's capable of outrunning Kinnosuke in a race and an accomplished tennis champion in high school.
  • The Ace: He's great at pretty much anything he does - academics, sports, cooking, medicine, washing babies, etc.
  • Aloof Big Brother: Played very straight. Uncommonly, he's one of the two main characters and this.
  • Arranged Marriage: Self-arranged to Christine Robbins for his father's company. It's subverted though.
  • Betty and Veronica: The "Archie" for Kotoko's "Betty" (Book Dumb and relatively nice) and Yuuko's "Veronica" (Academic Athlete and cold). In the end, Naoki chooses Kotoko.
  • Big Brother Instinct: Whenever his brother is endangered, Naoki becomes protective.
  • Bishōnen: He's the resident Mr. Fanservice with those tall figure, dark hair and grey-purple eyes Lucky him.
  • Brilliant, but Lazy: He's able to get the top class score on exams but he doesn't study at all in high school. He gets better, especially concerning medicine.
  • Brooding Boy, Gentle Girl: The sullen, cranky Brooding Boy to Kotoko's sweet, encouraging Gentle girl.
  • Cannot Spit It Out: A lot of grief would've been avoided had Naoki simply voiced his growing feelings for Kotoko earlier. It took a Green-Eyed Epiphany to finally declare to her.
  • Chick Magnet: Just ask Kotoko, Matsumoto, and the many other women who flirted with him.
  • Color-Coded Eyes: He has cold grayish-purple eyes that fits his demeanour very well.
  • Covert Pervert: He never seems to be interested in girls as far as his family and schoolmates know but it's what Kinnosuke assumes about him, fearing that someday he'll try something pervy on Kotoko.
    • He himself exploits this by acting like a Memetic Molester (he pretends to want to have sex with Kotoko) to scare her away as she sneaks in his room to steal his homework;
    • Also occasionally gives teasing or straight-up rude comments on Kotoko's looks or appears to know her exact body measures (Kotoko rightly wonders how can he be so accurate). When it's not mere trolling may very well be a sign of his attraction, since he's never seen to do this to any other woman despite being a Chick Magnet;
    • When the two of them are stuck in his flat during a storm and There Is Only One Bed, he teases her about the possibility of having sex to make her uncomfortable. He won't since it's her exactly his mother's plan to have them sleeping together. Mind that he never says it's because he doesn't want to;
    • After proposing to Kotoko they are talking about his feelings before going to sleep and Kotoko express her disbelief and that she would wake up the next day with Naoki still not loving her. Then Naoki suggests they could sleep together, with Kotoko freaking out. He then says they'll save it for another day;
    • Although his behavior with people and Kotoko is not that changed, after marriage he's clearly rather enthusiastic about making love with wifey.
  • Crazy Jealous Guy: Downplayed and deconstructed. For the former, he becomes only irritated, not "crazy" when Keita Kamogari, a nursing friend of Kotoko's, takes an interest in her. However, for the latter, the very fact that Irie doesn't understand why he was feeling the way he was feeling (not knowing the feeling of sadness or jealousy before) has him revert back to being a cold jerk to Kotoko again. Thankfully, he wises up.
  • Deadpan Snarker: He often delights in snarking at Kotoko's lack of common sense and poor performances at school. Being usually Surrounded by Idiots (average humans actually) does make him develope a sardonic sense of humour.
  • Defrosting Ice King: It takes over a decade, but he goes from cold jerkass to loving husband and caring father.
  • Deuteragonist: He's the male lead and goes through a Character Development as much as (or perhaps even more than) Kotoko. It's pretty much his story as much as it's hers.
  • Disposable Fiancée: To Christine. He technically got engaged to Kotoko when he still hadn't officially broken off the engagement with Christine. Luckily, Christine didn't really want to marry him either. The only reason drama existed at all was Christine's father who wants her to have an Arranged Marriage.
  • Dull Surprise: His rare shifts of facial expressions are visible almost only to viewers. It's justified since he has a reputation for being The Stoic.
  • Embarrassing Old Photo: Has tons of these, courtesy of his mother. The mother wanted a daughter, but was shocked to discover a boy, and had the newborn wear girl's clothing. Kotoko's first tutoring sessions with Naoki are a result of her Blackmail regarding a photo she was given by his mother.
  • Enraged by Idiocy: Naoki even loudly tells Kotoko's friend group he doesn't like stupid girls in high school. It even rubbed off on his younger brother, Yuuki. He gets better though.
  • Even the Guys Want Him: We can't blame Motoki for being all over Naoki, hmmmm? He even founded a fan club.
  • Faux Fluency: He supposedly speaks Surprisingly Good English as far as any other character is concerned, but his actual dialogue is quite grating and somewhat broken.
  • First Love: Naoki is Kotoko's and was also her First Kiss. Word of God confirms that Kotoko was his.
  • Freudian Excuse: Word of God confirms that being dressed up as a girl by his mother and finding out he was not supposed to dress like that (in kindergarten, no less) has left an emotional scar on him, crippling his relationship with people in general and girls in particular and coped with the fear of being ridiculed by being icy to everyone.
  • Green-Eyed Epiphany: The suggestion of Kotoko giving up on him for good and marrying Kinnosuke is what made Naoki finally snap and declare his love and desire to marry her.
    Naoki: Don't tell me that you love any other man.
  • Happily Married: To Kotoko, plus Babies Ever After.
  • Hospital Hottie: Becomes this after following his dream and becomes a doctor. The patients love his examinations.
  • Improbably High I.Q.: Even he acknowledges he must be really a genius after managing to get a perfect score on his college entrance exam despite being drugged up on cold medicine and only having half an hour left to fill in the answers.
  • Insufferable Genius: Tall, Dark, and Snarky Variant - Very smart, but such a Jerkass. He gets better.
  • Jerk with a Heart of Gold: And hides it very well. This would not stop him from caring for the people he's closest to.
  • Loving Bully: His endless teasing of Kotoko has an element of this. His Disposable Fiancé Sahoko rightly sees through it, saying that the always impeccable Naoki shows where his heart is when he's mean to Kotoko.
  • Master of the Mixed Message: The entire first arc has Naoki being first extremely cold, then unexpectedly gentle, and switch again to cold and even rude, much to poor Kotoko's confusion. It takes a huge Green-Eyed Epiphany to finally show his true feelings.
  • Not Distracted by the Sexy: Immune to Yuuko's sexiness, can't be seduced by nurses or in Hawaii.
  • Not So Stoic: Anytime anyone close to him is actually hurt or in trouble. Kotoko becomes his chief source of this.
  • One Head Taller: He's considerably taller than Kotoko, which leads to Cry into Chest quite often.
  • Photographic Memory: Remembers things in great detail after reading them once. Because of this, he has Encyclopaedic Knowledge. He also believes learning like this is normal.
  • Shipper on Deck: In the anime he's the one who suggests that Kinnosuke should propose to Chris. Also he's amused by the dynamic between his little brother and Konomi.
  • Single-Target Sexuality: His absurdly high I.Q. has made him bored with everything and everyone, so though many others have tried and he even appears to date Matsumoto and plans an Arranged Marriage to Christine Robbins (Sahoko in the manga), it takes more than a pretty face to impress him. And that's why the only one who even meant something to him is Kotoko, and he's loved her and only her for a long time.
  • The Smart Guy: Naturally, as The Stoic and The Ace with a Photographic Memory.
  • The Stoic: Very rational and shows little emotion. At least a first, Kotoko softens him.
  • Sugar-and-Ice Personality: It takes a while to see a caring side behind his usual aloof, arrogant demeanor.
  • Supreme Chef: Can become this by just reading cooking books. Was doing professional-level things the first time he tried. He prefers others to cook for him though.
  • "Take That!" Kiss: Kisses Kotoko for the first time to get back at her after she publicly humiliated him with his childhood photo.
  • Tall, Dark, and Snarky: Being a Insufferable Genius gave him a sardonic sense of humour to match his ''very'' good looks.
  • Teen Genius: He starts at this. Naturally it no longer applies as he becomes an adult, but still a genius.
  • Troll: Naoki often delights in taunting Kinnosuke about Kotoko's feelings for him, when he's not trolling Kotoko herself in various occasions.
  • The Ugly Guy's Hot Daughter: A son example. Only his wife's genes could explain how plain Shigeki could have a ridiculously hot son. In the first episode Kotoko thinks that this Irie could not be Naoki's father before Naoki shows up. Kotoko's father even says in the manga that luckily for him, Naoki took after his mother.
  • Uptown Guy: Naoki (born into an upper class family) and Kotoko (born into a lower-middle class family).
  • Wacky Parent, Serious Child: The Defrosting Ice King to his mother's Genki Girl.
  • What Does He See in Her?: Constantly wondered by people. Even lampshaded by Kotoko's own father, Shigeo, after he asks his permission to marry her. Quote 

    Kinnosuke Ikezawa

An expressive and excitable idiot who wears his heart on his sleeve.


  • Book Dumb: Along with Kotoko and their classmates, there's a reason for ending up to class F. Although his classmates managed to get accepted to university thanks to Naoki's tutoring, he was too proud to ask for help and ended up the only one who would not go to university. He's not bothered since he decided to become a Supreme Chef.
  • Brooding Boy, Gentle Girl: The Brooding Boy to Christine's Gentle Girl, since when he meets her he's still brooding about Kotoko's marriage.
  • Butt-Monkey: Often the butt of the joke due to his foolishness.
  • The Chew Toy: He's the character most likely to have Amusing Injuries due his Butt-Monkey status.
  • Did Not Get the Girl: Since Naoki is the the male lead, it's rather obvious he eventually wouldn't. The second time he gets better.
  • Drama Queen: He could get hilariously hammy in his reactions to things and people.
  • Dumb Muscle: He's so strong he managed to dig Kotoko's father out of the hus house's rubble by himself, but he's also the most eager to do something foolish.
  • The Fool: Foolish and academically-incompetent but he means well and tries hard.
  • Greaser Delinquents: He and his posse in high school are drawn this way, but it's downplayed.
  • Happily Married: To Christine Robbins, plus Babies Ever After.
  • Hair-Trigger Temper: The guy looses it very easily.
  • Hidden Depths: He may seem a lazy, loud, idiot from Osaka but as his employer notes, he's an hard worker and good at his job. He can also act quite noble, when his sense has the best on him.
  • Hopeless Suitor: For Kotoko. After Naoki's engagement to Christine, he does get a few dates though.
  • The Idiot from Osaka: Literally. He's an idiot from Osaka who speaks with a heavy Kansai accent.
  • If You Ever Do Anything to Hurt Her...: When it turns out that Kotoko is going to marry Naoki, he says that he'd better treat her well, otherwise he'll take her away from him.
  • Kansai Regional Dialect: He speaks this way and it's very pronounced.
  • Like Brother and Sister: He didn't get Kotoko, and eventually married another woman but they still have a strong friendship of this kind.
  • Race for Your Love: He tries to reach out Christine before she flies back to England, but doesn't get her in time. Luckily for him, she had already decided to stay.
  • Start My Own: After years of apprenticeship, he's eventually able to open his own restaurant.
  • Supreme Chef: Becomes this after apprenticing for years under Shigeo, Kotoko's father. Eventually opens his own restaurant with Christine.
  • Throw the Dog a Bone: After losing Kotoko to Naoki, he eventually becomes Happily Married with Christine and starts his own successful restaurant.
  • Tsundere: He's rude in his first interactions with very much smitten Chris, justified since he's just recovering from an heartbreak and would eventually warm up to her, but still doesn't show his affection blatantly.
    • Also after years of rivalry, he somewhat comes to consider Naoki a friend, but he would never say that out loud.
  • Ugly Guy, Hot Wife: Him and Chris. While he's not ugly, he is funny looking, while she's just drop dead gorgeous.

A beautiful, high class blonde. Her father runs a large bank and her mother's a Hollywood actress.

  • The Mourning After: He still very much loves his wife, never remarried and raised Kotoko alone, saying to his son-in-law Naoki that for all her wackiness he could never wish for a better wife. He even takes the risk to come back to his home during an earthquake to save his wife's photo.
  • Open-Minded Parent: Actually takes Kotoko's opinion and accepts various things other parents would at least criticize somewhat.
  • Savvy Guy, Energetic Girl: He and is late wife Etsuko seem to have shared this dynamic. He was the down-to-earth guy to his wacky wife, who resembled her daughter to a T.
  • Shipper on Deck: Downplayed. Early on, he seems to be colluding with Mrs. Irie's shipping plans to some extent, though he tries to have Kotoko giving up when he thinks she cannot succeed. Later, he offers his son-in-law Naoki some good advice regarding Kotoko and Naoki's strained marriage.
  • Supreme Chef: He's a chef with many years of experience and training. Everything he makes tastes extremely good.

Voiced by: Naoko Matsui
Portrayed by: Miyoko Asada (1996 J-Drama), Zhao Yong Hua (2005 Tw-Drama, 2007 Tw-Drama), Jung Hye-young (2010 K-Drama), Tomomi Nishimura (2013 J-Drama, 2014 J-Drama), Inthiporn Yuenyong (2015 Th-Drama), Hikari Ishida (2016 J-Movie)

Naoki and Yuuki's mother. Loves photography and video.


  • Amazingly Embarrassing Parent: And how. Her smothering ways and Shipper on Deck behavior extremely embarrasses Naoki and sometimes even Kotoko. She's one of the funniest characters for this.
  • Camera Fiend: Nearly always with a camera, camcorder, or some type of photographic device. Takes pictures of everything. Her equipment ranges from miniature spy cameras to professional telescopic lenses on high-grade cameras. She also has tons of photo albums she puts them into.
  • Curtains Match The Windows: Brown hair and eyes.
  • Doting Parent: Dotes somewhat on Naoki and Yuuki, but intensely on Kotoko, as she always wanted a daughter.
  • Fat and Skinny: Skinny to her husband's fat.
  • Genki Girl: Extremely energetic and enthusiastic in everything she puts on her mind (most of the time is getting her son and Kotoko together)
  • Housewife: She's very domestic and enjoys it thoroughly. Also tries to teach Kotoko how to be one.
  • Information Wants to Be Free: At Naoki and Kotoko's wedding, she finally reveals Naoki's childhood photo to all the guests saying that since he's now married (and his wife already knows) she can finally free this weight off her shoulders. Naoki spends his entire honeymoon in a very bad mood for this.
  • Like a Daughter to Me: She instantly adores Kotoko as the daughter she never had.
  • My Beloved Smother: Though she is a well-intentioned one, her smothering ways with Naoki are probably the origin of his coldness (which she acknowledges with the embarrassing photo incident).
  • Nice Job Breaking It, Hero!: Her insane efforts in getting her son and Kotoko together are only keeping him away from her. Had she not pushed him to Kotoko at every occasion, he'd have probably declared earlier, since he never acted on his feelings because feared (not without reason) his mother would use it to control his life.
  • Paper-Thin Disguise: No one, even Kotoko, is ever fooled by Mrs. Irie disguises.
  • Parental Substitute: Kotoko's mother is dead and Noriko wanted a daughter badly, she and Kotoko basically adopted each other as mom and daughter.
  • Shipper on Deck: Extremely Exaggerated - Ladies and gentlemen, she is the Ship Captain. Nobody in-universe and out ships Kotoko/Naoki as much as her. Even before knowing about Kotoko's feelings for Naoki, she's saying they should get married. To this end, she tries to help Kotoko win her son's heart constantly, even up to giving an extreme cold shoulder to Christine Robbins and setting up a very elaborate wedding for Naoki and Kotoko's only two weeks after their engagement.
  • Strong Family Resemblance: In her family they all look the same and also her two sons greatly resemble her.
  • Ugly Guy, Hot Wife: She's way prettier than her husband, even in their youth. In the manga family friend Shigeo says to their son that he's lucky that he looks like her.
  • Unwitting Instigator of Doom: Keeping to have her little boy dressed up as a girl led to rather traumatic discover of gender roles for Naoki. She (rightly) blames his coldness on this.
  • Wacky Parent, Serious Child: She's the Genki Girl to her Ice King son, and to a lesser extent her youngest son qualifies as well.
  • You Keep Using That Word: She mainly refers to her son, Naoki, as "oniichan" regardless of context, when it's generally used by a younger sibling to refer to an older/elder brother.

Voiced by: Romi Park
Portrayed by: Ryotaro Akashi (1996 J-Drama), Zhang Bo Han/Son Yang (2005 Tw-Drama, 2007 Tw-Drama), Choi Won Hong (2010 K-Drama), Yuga Aizawa/Yoshiaki Miyagi (2013 J-Drama, 2014 J-Drama), Yukung Watanabe (2015 Th-Drama)

Naoki's younger brother and basically a miniature version of him. Intelligent, but hot-headed, unlike his cold older brother. He has sandy brown hair darker than his brother's.


  • Annoying Younger Sibling: Downplayed. Is this to Naoki at times, mostly when he wants to be alone.
  • Big Brother Worship: Has a serious case of this in his younger years. He idolizes Naoki and emulates him. He's lucky to be smart almost like him, otherwise he would be ridiculous. In the manga he even is content to be one day his brother's Number Two at the Family Business though he's the one actually interested to the job. After Naoki Took a Level in Kindness, he discusses with him that he admired his cool demeanour, but admires him even more now that he learned to pursue his dream and even start a family.
  • Bishōnen: Grown-up Yuuki is easy on the eyes much like his big brother.
  • Bratty Half-Pint: Other than being an Annoying Younger Sibling to Naoki, he's this to Kotoko and her clique, teasing them for being Book Dumb and being generally unfriendly. Thankfully he grows out of this as he gets older.
  • Brilliant, but Lazy: Downplayed. He's very smart and quite lazy, but less so than Naoki on both accounts. He pretends to put little efforts in his studying mostly to emulate Naoki.
  • Child Prodigy He's an extremely smart kid, tough he's more of an hardworking than his Brilliant, but Lazy big brother. He has already a reputation in elementary school and then in junior high.
  • Deadpan Snarker: Along with his big brother, he's usually very sarcastic towards Book Dumb Kotoko.
  • The Dutiful Son: Plans to take over the Family Business so Naoki doesn't have to worry about it and can become a doctor like he wants. He's fine with this since, as Kotoko finds out, he has been always more interested than Naoki, but was content to be his big brother's Number Two since he was the second son.
  • Enraged by Idiocy: Picked up by emulating Naoki. He gets much better, especially toward Kotoko after she saves him multiple times and to Konomi as he befriends her.
  • Green-Eyed Epiphany: When in their teens Konomi gets popular with boys, he finally snaps and tells her to tell her suitors she already has a boyfriend. He's not his big brother's Junior Counterpart for nothing.
  • Insufferable Genius: He's smarter than most older people and doesn't let anyone to forget this. He grows out of this while getting older.
  • Oblivious Younger Sibling: He hadn't the slightest idea about Naoki's Embarrassing Old Photo incident (justified since he wasn't born yet) and he's shocked to find out. But subverted regarding big brother's feelings for Kotoko. He was one of the firsts who knew.
  • Oh, Crap!: Has an hilariously epic moment of this when he catches his big brothers kissing Kotoko in her sleep.
  • Precocious Crush: He has a brief one for Kotoko's coworker Tomoko, but he falls out when he's creeped out by her fascination with gore.
  • Red Oni, Blue Oni: Despite being very much similar, Naoki is a cold and collected, Yuuki is more brash and a bit of a Tsundere.
  • The Resenter: Other than being Enraged by Idiocy, the reason he doesn't like Kotoko at first is that he was kicked out from his room to make space for her, and also because he senses she's stealing attention from his mother and his brother.
  • Savvy Guy, Energetic Girl: The savvy to Konomi's energetic girl. First as friends, then as a couple.
  • Secret Keeper: He's the first one who learns that Naoki actually loves Kotoko, when accidentally saw him kissing her while asleep.
  • Shipper on Deck: Yuuki later comes to support Naoki and Kotoko becoming a couple after being the first one who finds out that Naoki loves Kotoko back.
  • Strong Family Resemblance: He's basically a mini version of Naoki. He grows to look more and more like his older brother as he ages.
  • Tsundere: A rare male example. He's somewhat more Hot-Blooded than his infamously ice-cold brother but has a cute side, though he pretends not to. The best example are his interactions with Kotoko and Love Interest Konomi and even better when has a fight with friend Nobuhiro, punches him and then forgives him but still pretends to want to punch him.
  • The Ugly Guy's Hot Daughter: A son example. Pretty much like Naoki, he luckily takes after his mother and grows up quite the looker.
  • Wacky Parent, Serious Child: Like his brother, Yuuki is far more composed then their Genki Girl mother.

  • Satellite Character: He is only seen hanging around Naoki.
