B Group no Shounen

Sakuragi Ryo sees high school as divided into three ranks: the attractive, smart, and athletic students in group A; average students in group B; and the students everyone ignores in group C. In middle school, he was pushed into group A against his will, so as he starts high school, he is determined to stay in the background and enjoy a quiet, uneventful school life as a member of group B. One evening, Ryo finds three delinquents surrounding a girl. Though he hopes to avoid getting involved, he steps in because she needs help. The girl he saves is the prettiest student at his high school, and she wants to repay him. Now Ryo must do everything he can to keep the rest of the school from noticing him and upsetting his place in group B.
