After class loner Yano Megumi misses school for a few days her classmate Igawa comes to deliver her homework and tell her about an upcoming test. He ends up discovering that she’s a secret Otaku, and a “rotten” yaoi fan who’s been skipping class to draw doujinshi of men getting it on. He volunteers his own nudity as an artistic reference in a classic case of “I’ll show you mine if you show me yours.” Sensing the two of them getting closer, Igawa’s childhood friend and class president Fukuhara Shinobu is jealous. A friendly rivalry between Yano and Fukuhara erupts. Spoiler: the winner is Igawa.
