Read Kou 2 ni Time Leaped Shita Ore ga, Touji suki Datta Sensei ni Kokutta Kekka Manga:
I was a corporate worker in my 30’s, when I woke up and found that I had time leaped to the spring of my second year of high school. At the time, there was a teacher that I had regretted not confessing to, so I confessed to her in the heat of the moment, and now we’re dating! However, the teacher is one who would make any man a good for more.. nothing person, so I end up being spoiled by her a lot.
