Moe Kare!!

A 2005 manga.

Hikaru Wakamiya is a 15 years old girl that reads too much shoujo. And by that we mean she dreams to find a "prince", a handsome kind man of the kind that, um, seems a little unrealistic – you know, the kind you would only find in a shoujo actually. One day, she seems to meet a guy that seems to be like that when he repels a group of bullies along her (more or less), but the guy is a perverted individual that soon after kissing Hikaru (using his tongue!) dismisses her because she lacks volume on the front and the back, if you know what I mean.

In the next Saturday, she goes in a group date with her friends where she meets a guy who looks almost exactly like her "perverted prince", except for the fact he's not that perverted and has black eyes instead of her "perverted prince"'s blue.

Having initially misunderstood him for the individual that took her mouth's virginity, Hikaru decides to apologize to this boy, Takara. But as she begins to know him, she begins to realize she may be falling in love...

Tropes used in Moe Kare!! include:

Badass: Arata and Taraka both qualify for their fighting ability.
Bishonen: Arata and Taraka since they're basically twins.
Establishing Character Moment: Arata's first scene shows he's kind (helps a boy being bullied), badass (kicks bully's ass), perverted (kisses Hikaru without even asking permission) and shameless (comments about her lack of... erogenous attributes).
Even the Guys Want Him: Yep, Taraka has some male fans.
Grievous Harm With A Body: Arata uses Hikaru's body as a weapon to hit bullies, we're not kidding.
Intimate Healing: Taraka gives Hikaru's medicine orally since she's too weak to drink by herself after she collapses out of sickness just before she was going to do an entrance exam.
Jerkass With a Heart of Gold: A weird case where the "heart of gold" part is shown before the jerkass one with Arata. He helps a kid being bullied, but soon after kisses Hikaru without permission and soon after dismisses her like nothing, leaving the girl heartbroken.
Nosebleed: Hikaru has one when she sees Taraka's abs.
Sacred First Kiss: Hikaru laments that her first kiss was with Arata after he shows his...less than heroic qualities.
Visual Pun: A literal little chick appears on Hikaru's thoughts balloons when Arata calls her "little chick".
