I'm looking for a manga where the female protagonist act like an asshole but she actually a nice girl.

Maybe people call her a B*cth or a Slut because of her looks. She was tired of people call her all that, so she just act like what people think she is, but actually she doesn't have her first kiss yet..something like that 🙂

I prefer shoujo

no yaoi/yuri
no mature/ecchi
no psychological

I hope someone can help me 😀

Akuma to love song ? You have to give it about 5 chapters before you can tell she's actually a "nice" girl.
And ummm maybe
Okoborehime to Entaku no Kishi But this one is more like, she acts brave and as a playgirl(?) to advance in her position.
Ou-sama ni Sasagu Kusuriyubi

thanks, but I already read Akuma to love song. 🙂

anything else ?
