Skip Beat! for shojo romance junkies like me <3
It's about an innocent young girl named Kyoko who gets heartbroken by a rockstar named Sho. Kyoko's inner emotional innocence becomes twisted, and refuses to love anyone ever again. To avenge herself against Sho, she plots to get more famous than him, and gets involved in the TV busniess. She also meets a super famous male actor named Ren, whom is Sho's worst enemy. Pretty slow in the beginning, but the cliffhangers come one after another once you get into it.

edit: omg just saw someone else recommended it-- HOLLLAAAAA
