Himari Uehara is excited to be attending an all-boys high school so he can avoid girls, whom he has always found frightening and difficult to understand. Before long, he meets his soon-to-be closest friend and confidant, Gaku Asada. When Uehara—who only lives with his sister and mother—is worried that the mess in his pants after he wakes up is a sign of a serious medical condition, he turns to Asada for guidance. Asada is quick to inform Uehara that he is merely experiencing wet dreams and also gives him some hands-on experience relieving his sexual frustration. However, as their bond becomes more intimate, they wonder how long they can consider their activities to be merely that of friends. [Written by MAL Rewrite]
