High schooler Masahiro Setagawa is a fairly helpless delinquent, so much so that the neighborhood bullies use him to run their errands. His life changes when he meets high school teacher Kosuke Oshiba.

It's two romance stories involved with each other. Three high school boys and a teacher. One of the boys is involved with gangsters, the teacher and one of the boys are siblings and two of the boys are childhood friends. It's a shounen Ai where we get to see the romance develop and the growth of the characters.
