Hey, I'm looking for a shoujo manga (i think, it's romance for sure though) about a boy who did something bad to his girlfriend the year before (in middle school?) and afterwards, stops talking to her (and everybody else) because he doesn't want to hurt her again. The manga begins in a new school year, and the boy always listens to music very loudly and so that he can't hear either her voice or the people talking about them (i don't remember).

I read this a few years ago, so the story is quite hazy in my mind. I'm not sure if this is enough to find it, but I'd be really happy if someone knew. ^^ Thanks!

was it Aishikata mo Wakarazuni? i only remembered because the cover was of a guy wearing headphones.

eeks! sorry for the late reply, but ya it is ^^ thanks so much~
