you know I don't think she was stealing him she even changed her school choice to a different one from the boy... she just wanted to tell him her feelings and be rejected and to walk with him one time at least, if he didn't like it he should have told clearly (at the end it's obvious he wanted to)
But the stupidest thing is the GUY. I really Don't blame the girl but the GUYS IS JUST SO STUPID . I WOULD HAVE KILLED HIM IF I was the girlfriend.

I'm not so pleased with the last side story. I hate girls who try to steal other girl's boyfriend. Self-pity and didn't care about the other party's feelings,she's a pretentious bitch. And he's a bastard,why didn't he break it off with his girl in the first place? I will definitely punch him hard if I'm his girl.
Is it cool that this situation always arise in Japanese school life? It happens most of the time in mangas till I'm thinking that this must be the norm in Japan...
