Do m, inran, hoshigari. Zenbu sensei no koto desho? by Tomo Mitsuhashi

Summary

Plot: Akito Takaoka spends his days teaching classics to high school students and his nights having meaningless one-night stands with other men. Last night was supposed to be just another fling, but when he wakes up, the cute guy next to him laughs and says, “So you really didn’t recognize me?” Akito can’t believe it… He actually slept with Shindo… one of his students! Shindo continues to pursue Akito while at school, and though Akito vowed never to get romantically (or physically) involved with a student, Shindo’s gaze alone sets his blood aflame. He knows it’s wrong, but he wants more…!
