Jirou joins the friend group when it is discovered he is tagging along after Masahiro without him knowing. He hangs out with the group of friends and comes for dinner served at the Ohshiba home often.

Later, he is the last student at school while Masahiro and Kousuke are together and think they are alone. He believes the two are fighting and hides in a broom closet, only to see them kiss. This results in Jirou revealing their secret love affair to the other guys, and drama ensuing between Masahiro and Fukushige.

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 Kousuke Oshiba, a man whose fighting abilities have earned him a powerful reputation on the streets. Oshiba finds himself with a desire to protect Setagawa, and despite swearing that he's not interested in men, Setagawa finds himself getting more involved in Oshiba's affairs...

Note: Contains an extra chapter.

Masahiro Setagawa doesn't believe in heroes, but wishes he could: he's found himself trapped in a gang of small-time street bullies, and with no prospects for a real future. But when high school teacher (and scourge of the streets) Kousuke Ohshiba comes to his rescue, he finds he may start believing after all...in heroes, and in his budding feelings, too.
