Tonari no Kaibutsu-kun

Mizutani Shizuku is the type of person who only cares for her own grades. But when she accidentally delivers lesson notes to Yoshida Haru, he becomes convinced they are friends. Haru turns out to have a very innocent personality, but who would've thought that Haru would actually confess to Shizuku? A cold-hearted girl and super-troublemaker romance with a fresh new perspective.
