8	!!Tropes in the show include:
9
10	* AdorablyPrecociousChild: Tomoya is a little younger than his sister Ichika, and definitely a lot shorter. And he certainly seems more mature than her.
11	* AllLoveIsUnrequited: Ichika seems to be in love with Tomoya, but he only considers her a sister, and in turn Tomoya is in love with Fujisaki, who only has eyes for Kouki, while Kouki only has eyes for Ruri.
12	* BeachEpisode: Well, it's a pool, but the girls are in swimsuits in episode 5 because of this.
13	* BitchInSheepsClothing: Fujisaki, she pretends to be nice to be popular but is actually a narcissist, and although she eventually becomes nicer to Tomoya, that doesn't stop her from pretending to have feelings for him to piss off Ichika, or use him to get closer to Kouka.
14	* BreakTheCutie: Fujisaki's past reveals she was bullied, and even when she tried to be nice as told to by a teacher, boys still treated her with contempt.
15	* BreastAttack: Ichika slaps Marina's breasts after Tomoya stares at them in episode 3. She is understandably confused at the sudden smackdown.

18	* ButNotTooForeign: Marina is a quarter Russian, while her cousin is half.
19	* BuxomBeautyStandard: Marina is well-endowed causing her to attract a lot of unwanted attention from the boys. Ichika mostly [[ACupAngst looks at them with envy]], and tries to downplay them in episode 9 by saying that "just being big is meaningless." The former [[LampshadeHanging immediately asks]] where she was looking when she said that.

22	* ChickMagnet:
23	** Kouki, who gets a lot of valentine's day chocolate from the girls in their school.
24	** Subverted with Souichirou Fuji, he is so handsome that many women are attracted just by looking at him, but that attraction quickly disappears when he starts talking about his otaku tastes.
25	* ClingyJealousGirl: Ichika, who slaps her friend Marina's boobs after Tomoya sees how big are. She also doesn't like Fujisaki due to her being in the same class as Tomoya, and especially because he seems to show some interest in her.

31	* TheFriendNobodyLikes: Mitsuru, being so perverted, earns everyone's displeasure, and is only tolerated for being Tomoya's best friend, and even Tomoya himself questions why he is still friends with him.
32	* GratuitousEnglish: Marina's brother in episode 5 asks if Tomoya or Ichika can speak English. She replies that she can, then they switch over to Japanese for the rest of the episode.

35	* ImaginaryLoveTriangle: Although Fujisaki and Ichika have a real rivalry, Ichika assumes that it is because she wants to "steal" Tomoya from her, although in reality Fujisaki is not interested in him, even so she is often willing to pretend in order to make Ichika angry.
36	* LoopholeAbuse: In the first episode, Tomoya hangs a sign in front of his door saying he'll stop talking to her if Ichika enters that way. So she tries to enter from the window instead.

39	* NotSoDifferentRemark: Kouki gets off on the wrong foot with Tomoya in episode 4. However, their sisters arrive, and while Ichika tries to comfort Tomoya, Ruri, Kouki's sister, beats the living daylights out of him. Although both are treated vastly differently, Tomoya kind of understands that Kouki also has difficulty with an older sister as well.
40	* ObliviousToLove: Ichika does not recognize any man who is not her stepbrother, which makes her not understand why some men gave her cookies on Valentine's Day, to the point that Tomoya can't help but feel sorry for them.
41	* {{Otaku}}: Marina's cousin is one, which is revealed when he excitedly talks about how Ichika resembles a girl from a game he's played.

50	%% * ValentinesDayEpisode: Episode 10.
