Kou 2 ni Time Leaped Shita Ore ga, Touji suki Datta Sensei ni Kokutta Kekka

A man in his 30s, working in corporate, discovers he has time-traveled to the spring of his second year of high school. He had once regretted not confessing to a teacher, and now, in a moment of impulse, he does so, and they begin a relationship. The teacher, however, is known for making men lose their drive, and he finds himself being indulged by her. As they keep their relationship a secret, he balances school life with his feelings for the teacher, who is also overworked. His inner 30-year-old self contrasts with his role as a high school student, creating a daily romantic comedy.
