APNS-274 I haven’t even kissed my classmate boyfriend yet… I think I probably seem pretty serious… but the truth is, I’m into older men… no, into middle-aged men… Tachibana Hinano

Hina, a schoolgirl, recently got a boyfriend and was a quiet honor student who believed in a pure, wholesome relationship. However, she had a vivid imagination and spent her days lost in fantasies, imagining intimate encounters with older men and indulging in private self-pleasure. She cared for her boyfriend, Yugo, but could not bring herself to direct romantic feelings toward him. Then one day, she is attacked in her sleep by a neighborhood man named Koji, who had come by with a circular notice, and the two become intimate. This incident leads her to fall into a decadent lifestyle, eventually involving Koji’s drinking companions as well.
