I'm 読書 the books, I haven't seen the show. And I'm only up to book three, so, I could be very off here.
Vampire Knight. It's not quite the "main" character I dislike, even. He's one of the main characters. I really think Yuuki's pretty cool. I don't like Kaname that much. I'm only up to book three, but I think he's just a little too... perfect. Like... like Peeta in The Hunger Games! TOO PERFECT! It bothers me! So I have to keep 読書 until I can find a flaw. With Peeta, the only flaw I could find was that he's basically an idiot (compared to Gale ;) and it bothered me so much.
