Boku wa Kimi to Koi ga Shitai

Souta is a handsome high school boy who's always dreamed of being the hero who saves the heroine. So he never imagined that he'd be the one that needs saving. One day, while riding on the usual crowded train, he finds himself at the mercy of groper. Frozen by fear, he's rescued by a dashing older boy, who then gently comforts the shaken Souta. Souta can't stop thinking about this kind stranger, who's the exact ideal he aspired to be. That is, until he meets the gruff new transfer student, Hanagata Sakuma. But wait, isn't that the "Oniisan" who saved him? And why is he acting so mean?? (Source: Charles Comics, translated) Note: Includes one extra chapter.
