START-653 | Am I not allowed to fall for a student? A student kept hanging around the infirmary every single day just to see me—and as I turned them into a sex-crazed pervert, I found myself unable to let them go. — Riko Hoshino

Sugiura is a student who skips class to spend his days in the school infirmary. He has developed romantic feelings for the school nurse, Minami. Seeing right through him, Minami teases him with kisses—but eventually, Sugiura’s pent-up emotions boil over, and the two cross the line. From then on, Minami repeatedly engages in sexual encounters with Sugiura on school grounds; however, the day for her transfer to another school is fast approaching.
