What are some bad boy and good girl anime's to watch? One with romance and ages 12-15?

I have seen lots where the girl has powers and a boy with her but I want one where she has magical powers but doesn't know it, then these 5 boys or however many come looking for her, then begin living in the same house together. And I would also like it if they begin to have feelings for her, and start protecting her, maybe with a bad boy character, a good guy, a strong guy, a cute guy or something like that. If you could answer this that would be amazing. It doesn't have to be exactly like what I have said but something possibly close to it. I'm not too sure if there are anime's like that but I would just like to know if there is.

If not, thanks anyway

AND AGAIN, THANKS SO MUCH!
I'd also like if they were really good anime drawings, and only gorgeous, cute girls and hot, cute guys, please!

THANKS
Also one more thing, they don't have to have special powers, but I thought that would help the plot or story

I really enjoyed Death note and Hell girl.
