I Wanna See You Smile (Karmagisa)
Nagisa's the kind of boy who never smiles or even laughs. Or maybe, well he used to, but his once happy life has turned into pure hell when a certain incident happened that the person so close to him is now gone. He faces abuse, depression, solitude, and suicidal everyday. He was always alone until he met Karma Akabane, the new student who swore to make him smile once again.
