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 are jealous. A friendly rivalry between Yano and Fukuhara erupts.
