Boku wa Kimi to Koi ga Shitai

Souta is a prince-like high school student who has always dreamed of being the hero who saves the heroine. So he never imagined that he'd be the one who needed saving. One day, while riding his usual crowded train, he finds himself at the mercy of a groper. Frozen by fear, he's rescued by a dashing and gentle Oniisan, who even comforts the shaken Souta. Souta can't stop thinking about this kind stranger, exactly the ideal he aspires to be. That is, until he meets the gruff new transfer student, Hanagata Sakuma. But wait, isn't that the face of the "Oniisan" who saved him? And why is he so mean??
