Hitorijime My Hero

Masahiro Setagawa no longer believes in heroes since he thinks they don't actually exist, especially given how much trouble he keeps getting into. He was forced to join a gang, and now he is frequently taunted and treated like a gopher boy. But shortly Kousuke Ooshiba, also known as the "Bear Killer," a notorious street fighter, unintentionally saves him. He also happens to be his current homeroom teacher and the older brother of his closest friend, Kensuke Ooshiba. Despite Kousuke's recent claim to be Masahiro's "underling" and his assurances of protection, the two appear to have feelings that go much deeper. Asaya Hasekura, a popular pretty kid who is reunited with Kensuke and who confesses his love for him, leaves Kensuke bewildered and uncertain.
