Tsubaki Hibino has a hobby: she likes styling her sister's hair. However, she doesn't think that style suits her and keeps her own hair in braids. At the start of her high school life, she's ready to find love, promising herself to become more fashionable and cute.

...Except she can't bring herself to it. On the first day in her new school, she finds herself bullied for her old-fashioned "Showa" taste in clothes. Even worse, she has to sit next to Kyota Tsubaki, resident [[TheCasanova casanova]] and the only one who managed to earn a higher score than her in the entrance exams. Angry at him, she cuts his long hair. This makes Kyota decide: she would be his next target. From there on, he ''would'' have her become his "woman".

''Kyō, Koi o Hajimemasu'', (''Today, Our Love Begins'', or the unofficial title proposed by Minami herself, ''Today, I Begin Love with Tsubaki''), deals with the developing relationship between [[NiceGirl "good girl"]] Tsubaki Hibino and [[AllGirlsWantBadBoys "bad boy"]] Kyota [[OneSteveLimit Tsubaki]]. The two start off despising each other, but quickly grow close as the series progresses. The manga is written by Kanan Minami, author of ''Honey X Honey Drops'' and began serialization in Shōjo Comic on 2008. It ended on November 2011, and has been compiled in 15 volumes.

The series has been adapted in a 2-episode OriginalVideoAnimation animated by JCStaff, a LightNovel presenting the story from Kyota's perspective and a live action series taking place a year before the events of the manga. A film was also released in 2012.

!This manga provides examples of:

* AManIsNotAVirgin: Kyota fits this trope to a T.
* AbusiveParents: Kyota's dad may be a respected teacher, but he's also extremely violent and constantly beats Kyota.
* AllGirlsWantBadBoys: Despite acting like a delinquent and switching girls like he switches shirts, Kyota is ''the'' most popular guy at school.
* AlphaBitch: Arisa and her GirlPosse react very badly when they find out Kyota has a girlfriend, physically assaulting and bullying her. She gets shaken when her actions almost cause Tsubaki to be raped.
* AlwaysSecondBest: Tsubaki can never beat Kyota in terms of academics because he scores higher than her every single time.
* AnguishedDeclarationOfLove: Tsubaki gives ''several'' to Kyota. Nako also gives one to Kyota when she sees that Kyota is persistent in returning to Tsubaki.
* ArtShift: The art style turns into comical chibis during comedic scenes.
* AttemptedRape: Arisa employs two thugs to scare Tsubaki during the marathon. To her horror, they try to go further than that and almost rape her. The timely appearance of Miho saves Tsubaki.
* BabiesEverAfter: A post-epilogue side story shows that Tsubaki is expecting her first child, a daughter.
* BastardBoyfriend: Kyota likes sleeping around, manipulating girls because he can't trust them, humiliating Tsubaki in front of their class and almost raping her. He stops doing most of those things after he begins dating Tsubaki.
* BeautifulAllAlong: Tsubaki's unattractiveness is emphasized through her conservative clothing choices and her BraidsOfAction. The film adaptation tries to make her look more homely by turning her into a {{Meganekko}} and giving a subsequent TheGlassesGottaGo transformation. The class is amazed by TheMakeover a quarter into the series and comments on her looking cute, when all she needed to do was let her hair down and wear her skirt shorter.
* BerserkButton: Trying to dig into Kyota's past or hurting Tsubaki can make him unleash his UnstoppableRage at you.
* BetaCouple: Sakura and Nishiki, of course.
* BigManOnCampus: Kyota is the president of the student body for scoring the highest on entrance exams, and he's also the most popular boy in school.
* BilingualBackfire: When Tsubaki first meets Halstead, she gives him directions in (broken) English, assuming he was a foreigner. It turns out that Halstead knows Japanese. He tries to tell her such, but she doesn't hear him and he goes along with it.
* BirdsOfAFeather: Tsubaki feels threatened by Kyota's relationship with Nako because both of them are interested in space engineering, and it gets worse when Nako develops a crush on Kyota because of such. The same goes for Kyota when Tsubaki begins working as Hiro's understudy, and Hiro begins feeling attracted to Tsubaki because of their common career goals.
* BitchInSheepsClothing: Poor [[spoiler:Rika]] seems so nice, timid, fragile and innocent...until we find out she uses her apparent weaknesses to sleep around, manipulate people and set herself as the victim, all the while laughing at the others' expense.
* BlandNameProduct: Chapter 37 has Tsubaki sitting in front of "Bear Bucks Coffee", which couldn't possibly have anything to do with Starbucks coffee or Tsubaki's love for bears.
* BroodingBoyGentleGirl: Kyota is the Brooding Boy to Tsubaki's Gentle Girl.
* ButNotTooForeign: Halstead's father is American while his mother is Japanese. This also lands him into the Japanese stereotype of foreigners being more physically intimate, which [[spoiler:Rika]] attempts to exploit.
* CannotSpitItOut: Kyota isn't very good at talking about his feelings, but he becomes more open to Tsubaki. Tsubaki, on the other hand, tends to keep her mouth shut when it comes to speaking her mind because she doesn't want to disappoint anybody.
* CareerVersusMan: A big issue that comes up with the final third of the series is what Tsubaki wants to do in the future, and whether she should put her dreams as first priority instead of Kyota.
* TheCasanova: Kyota flirts and sleeps around with many different girls, but has never had a girlfriend.
* ChickMagnet: Kyota is the most popular boy in school and has girls constantly following him even after he begins dating Tsubaki. Hiro Hananoi is also popular with the girls for being a famous hairstylist. A common complaint from Kyota's UnwantedHarem is how a plain old-fashioned girl like Tsubaki can attract so many good-looking guys.
* CornerOfWoe: Tsubaki ends up like this during the Christmas chapter because Sakura reminds her she has to stay and study. Complete with GhostLights.
* DelinquentHair: Tsubaki describes that her whole school looks like it's composed of delinquents. Kyota himself has long, unkempt bleached hair. It looks neater when Tsubaki cuts it, but it's still pretty delinquent-y. It actually contrasts his excellent grades.
* DoesNotLikeMen: Spear Counterpart: Kyota doesn't mind messing around with girls, but he can't really trust them.
* DoggedNiceGuy: Halstead is really devoted to Rika, and assures her that even if [[spoiler:Kyota sexually assaulted her]], he would still take her back.
* EmbarrassingFirstName: In chapter 33, Tsubaki tells Kyota that she hated her first name and was jealous of Sakura's name, but began to like it more upon dating Kyota.
* ExpositoryHairstyleChange: Tsubaki begins wearing her hair in different styles outside of her old-fashioned BraidsOfAction when Miho encourages her to dress more stylishly. In addition, Hiro used to look like a nerd, but after TheMakeover from getting an ImportantHaircut, he began to act more outgoing.
* ExtremeDoormat: Tsubaki often puts people's needs above her own, and is afraid of saying things that will bother or disappoint others.
* FlowerMotifs: "Tsubaki" means "camellia" in Japanese, so there's a lot of artwork using camellias some way or another.
* FoolishSiblingResponsibleSibling: Sakura is flighty, fickle, and somewhat rebellious, while Tsubaki is diligent, earnest, and obedient. Their mother trusts Tsubaki more because of this.
* ForcefulKiss: Kyota steals Tsubaki's first kiss this way. He repeatedly does this at the start of the series.
* FreudianExcuse: Kyota's distrust in women stems from [[spoiler:his mother for leaving his family. Oh, and also that nurse he befriended who basically traumatized him unintentionally with a PrimalScene]].
* FriendsWithBenefits: Kyota doesn't have a girlfriend, but he gets together with his senpai, Yuki, for sex.
* GoryDiscretionShot: Right after Kyota throws a punch at Halstead for hurting Tsubaki, the scene cuts to one of of Halstead's cats, who turns out to be licking ''Halstead's blood'' from its fur.
* GreenEyedMonster: Tsubaki becomes jealous when Nako, a girl from her cram school who not only has better grades but also has a lot in common with Kyota in terms of career prospects, gets close to Kyota. On the flipside, the same thing happens to Kyota when Tsubaki becomes an understudy to Hiro, a famous hairstylist.
* HandsomeDevil: Kyouta is this [[spoiler: at first. He gets better]]
* HardWorkHardlyWorks: Tsubaki studied very hard in middle school, but she not only failed the entrance exam to her dream school, Nariyoshi High, but was also beat out by Kyota in terms of exam scores.
* HeroicBSOD: Tsubaki gets several over the course of the series. The first notable one she gets is [[spoiler:after her NearRapeExperience with Halstead, where she discovers what Kyota could have done to Rika, making her wary of his true nature]]. The second is when [[spoiler:she realizes she may have created a setback for Kyota to accomplish his dream of becoming an astronaut due to her insecurity and selfishness]].
* IWantMyBelovedToBeFashionable: On Tsubaki's first date with Kyota, he takes her shopping for a new dress and heels to replace her ridiculous bear t-shirt and jeans.
* IWantMyBelovedToBeHappy: [[spoiler:Miho]] had a crush on Kyota, but continuously acts as a ShipperOnDeck for Tsubaki and Kyota. [[spoiler:Initially it was just an act, but when she came to realize that the two really did like each other, she backs off.]]
* ImportantHaircut: Several, actually, which isn't a surprise since hairstyling is a big part of Tsubaki and, subsequently, the series. Let's count them off, shall we?
** Kyota was originally a LongHairedPrettyBoy until Tsubaki whacks off a good length with her scissors out of frustration. This has caused her to become a target of his fixation ever since.
** Miho gets one when she decides to get over [[spoiler:Kyota]] and asks Tsubaki to be the one to cut her hair.
** Halstead gets one when he decides to get over Rika.
** [[spoiler:Kyota]] gets one when he and [[spoiler:Tsubaki]] temporarily separate.
* InNameOnly: Prior to ''[[PortmanteauSeriesNickname KyoKoi]]'' receiving a live-action {{film}} adaptation, [[Music/AKB48 French Kiss]] released a short live-action drama in 2011 with their second single "If", the theme song for the OriginalVideoAnimation. Note that the drama is set in a completely different setting because it takes place a year before Kyota and Tsubaki enter high school and focuses on three new characters (who happen to be fictionalized versions of the members of French Kiss) and their own love problems. If it weren't for the fact that the title related to the main series, it could have been passed off as a completely different drama series.
* KindheartedCatLover: Halstead is always seen with cats crawling around him, though whether he is kindhearted is questionable [[spoiler:at first]]. He seems to be a full-blown FriendToAllLivingThings since he attempts to bring a goat back with him on the school trip to Hateruma Island.
* LastNameBasis: Tsubaki insists on calling Kyota by his last name because it's the same as her first name.
* LoveAtFirstPunch: [[UnreliableNarrator Sort of.]] On the first day of school, Tsubaki retaliates to Kyota's bullying by cutting his hair. He becomes drawn to her when she finishes his haircut, but in later accounts, he tells Tsubaki he hated her when they first met.
* LoveAtFirstSight: Nishiki falls in love with Sakura at first sight.
* LoveConfession: Tsubaki sort of confesses she likes Kyota when they're alone looking at the stars. It backfires, as Kyota isn't interested in women who confess to him due to a traumatic experience he had in the past.
* LoveDodecahedron: Kyota has tons of girls after him, including his senior Yuki, Nako, and [[spoiler:Miho]], but he and Tsubaki are in love with each other. Hiro later develops a crush on Tsubaki.
* LoveRedeems: Kyota insists that he's changed from his past playboy ways because of Tsubaki. In fact, he tells Nako straight up that even if he had met her before he met Tsubaki, he would have dated her only as a part of TheBet because of his personality back then.
* MadonnaWhoreComplex: Tsubaki is the Madonna, a pure, NaiveEverygirl when it comes to love who wants to have sex after marriage. She is depicted as extremely conservative and naive. Meanwhile, every other girl who ReallyGetsAround is either a shallow AlphaBitch or a fickle, frivolous girl with no sense of responsibility.
* MasterOfTheMixedMessage: Since Kyota's doesn't outright state his feelings, sometimes Tsubaki feels as though he's leading her on.
* MissingMom: Kyota's mom left the family when he was young and allegedly cheated on his father, which is one of the reasons why Kyota can't trust women. [[spoiler:It turns out that she left because of Kyota's father's abusiveness and planned to take Kyota with her, but it just so happened that a detective Kyota's father hired took a photo of her boss giving her a CooldownHug, and that caused her to lose all custody rights to Kyota. Even though Kyota's mom had a good reason for leaving the family,]] Kyota is pretty much disconnected with her and refuses to even see her.
* MoralityPet: Tsubaki becomes one for Kyota, as she is often the one who tries to bring him back to his senses.
* MyBelovedSmother: Tsubaki's mother is overbearing and controlling towards her life mostly because Tsubaki is the oldest child in the family and shoulders the most expectations. Tsubaki's ExtremeDoormat and people-pleaser attitude only makes it worse.
* NaiveEverygirl: Tsubaki's very naive when it comes to socializing.
* NearRapeExperience: Kyota attempts to rape Tsubaki in chapter 5. He stops when she calls him out on manipulating a girl's feelings like that, but in an unsettling developement, ''[[UnfortunateImplications she starts feeling attracted to him after that]].''
** Halstead thinks to rape Tsubaki when they're alone in the classroom as payback for what Kyota did to Rika, but he ends up crying and lamenting on how he couldn't do such a terrible thing to a crying girl.
* {{Nosebleed}}: Tsubaki gets one out of embarassment when Sakura hands her smutty {{shojo}} magazines.
* NotSoAboveItAll: Tsubaki notes that even though Kyota acted like he didn't care about spending their first Christmas date together, he was in fact more excited about it than she was since he bought a candle and a gift for her early on.
* NotSoStoic: Kyota generally looks aloof and uncaring, but he loses his cool when it comes to Tsubaki, be it her awkward responses or making himself look like an idiot in order to help her.
* ParentalAbandonment: Kyota hates his father and regularly avoids him, while his mother left the family when he was young.
* PoorCommunicationKills: This happens a lot throughout the series because this is both their first serious relationship. Every five chapters something will come up that makes Tsubaki avoid Kyota (or vice versa) for a chapter.
* ReallyGetsAround: Kyota, of course, who often dates and has sex with his many FriendsWithBenefits. [[spoiler:Rika]] turns out to be this too, as she has a poor reputation at school for stealing people's boyfriends.
* RepetitiveName: Tsubaki hates that her first name is the same as Kyota's last name, but later grows to feel that the coincidence is special and even fancies the idea of having the name "Tsubaki Tsubaki." [[spoiler:She gets her wish when they get married at the end of the series.]]

* ShrinkingViolet: Tsubaki is very shy and quiet.
* SiblingYinYang: Sakura is outgoing, fashionable, and shallow while Tsubaki is a ShrinkingViolet, conservative, and responsible.
* StockShoujoBullyingTactics: Tsubaki gets bullied through isolation when she is the first to speak out against Kyota. When she begins dating him, she even gets beaten up by the AlphaBitch and her GirlPosse and receives tons of hate mail in her inbox with the subject, "Break up with him."
* ThirdPersonPerson: Sakura often speaks in third person.
* UnwantedHarem: Kyota is mostly indifferent to the flock of girls constantly following him, but uses them to his advantage whenever it benefits him. Sometimes he gets annoyed with them when they block him from seeing Tsubaki.
* ThemeNaming: Tsubaki and Sakura are both named after flowers. "Tsubaki" means "camellia" in Japanese while "Sakura" means "cherry blossom." In a post-epilogue side story, Kyouta proposes naming his daughter "Camellia" to continue the flower-themed naming.
* VisitByDivorcedDad: Or divorced ''mom'' in this case. Kyota's mother makes her appearance halfway into the series to convince him to live with her.
* WeUsedToBeFriends: Kyota and Halstead outright admit to each other that they can't be best friends like they used to when they were little, [[spoiler:until the situation with Rika gets cleared up]].
* WoundedGazelleGambit: [[spoiler:Rika]] likes pulling these, especially near Hal. When Kyota refused to sleep with her and said he dislikes women like her, she set it up so it seemed [[spoiler:he had harassed and raped her, giving her an excuse to break up with Hal and ruining their friendship.]]
* YouJustToldMe: Tsubaki tries to lie to Kyota that she was beaten up by Arisa and the other girls in the class... but accidentally reveals she was beaten up by them anyway.
