Inran JK to Saenai Ore

A plain and unremarkable high school boy finds himself surrounded by a group of attractive and forward gyaru girls. Despite his lack of confidence, these girls take an interest in him, pulling him into their social circle and a series of increasingly intimate situations.

However, his seemingly ideal harem life is constantly threatened by the arrival of other men—playboys, delinquents, and bad influences—who try to steal the girls away. As he navigates these relationships, he must confront his own insecurities and fight to keep the harem from being taken from him.
