I am an ordinary teacher, not famous, not handsome, and I haven't had a girlfriend for ten years. Suddenly one day, Momonogi confessed her feelings to me, but as a teacher, I had to refuse her affection. However, she still comes to see me from time to time, especially this time we even went out for dinner together. After a little drink, I felt a bit tipsy, and Momonogi invited me to a hotel to rest. I don't know why I couldn't resist her. And then, what was bound to happen happened, we crossed the final boundary. A teacher and a student together in a hotel, both of us blending into each other.
