Kou 2 ni Time Leaped Shita Ore ga, Touji suki Datta Sensei ni Kokutta Kekka (Light Novel)

Droning on as a corporate slave in my thirties, I woke up one day to find that I have travelled back in time to eleventh grade. I was in love with my teacher, Ms. Hiiragi at that time, and had always regretted graduating without confessing to her. Hence, now I shall do so—but she agreed!? I can’t believe we’re dating right now!! But, in the course of our dating, I found out that Ms. Hiiragi was the over-doting kind and ended up being pampered spoiled by her. Thus begins my secret flirty school life with my teacher who coddles me too much!!
