Inran Baby

Jouganji Heisuke is considered pretty hot by the girls in his middle school, but the one he has a crush on, Eguchi Chihiro, has no interest in him at all. He's pretty new to puberty and liking girls, and he is constantly surprised by how much every little thing she does turns him on. It's too bad that his crush is completely one-sided!
