Yu Aoyagi is rumoured around the dorm to have sex with anyone who asks. Although he confirms the rumours with a cheeky, “it feels better than going solo,” even he has standards. He doesn’t stay out overnight without permission, avoids clingy guys, and anyone not to his taste is out of the question. …However, he’s constantly breaking curfew. A persistant one-night-stand leads to him missing curfew one night, and the dorm superintendant ends up ordering him to clean the bathroom as punishment…… The calm and collected 28-year-old super Toriumi appears to see right through him. He’s heard the rumours going around about Aoyagi, but apparently has no intention of lecturing him……? A cat-and-mouse love game between a listless dorm custodian and an obedient but horny high-schooler!
