So, Ritsuka is the only character so far who doesn't have blonde/white/whatever light color hair. And he sat down next to a girl and instantly thought, "Wow, she's well endowed. And she looks stupid."
Those are the kinds of thoughts that I don't need to know about, okay? Especially when they're still introducing Ritsuka and trying to convince me to like him. :(
(I think I'm supposed to like him, anyway?)
