Boku No Kanojo Sensei

A brief description of the Boku No Kanojo Sensei manga: 

Because of my traumatic experience in the past, I have lost confidence in people called “sensei”. I was asked by the best and most beautiful teacher from my school, Fujiki Maka-sensei, to stay after school. “I… Love you”, uh, such a sudden confession. “Until you say you love me too, I won’t leave you alone.”

Ever since then, I’ve been left behind for “educational counseling”, where we’ve somehow watched adult videos and touched each other and dated. Over time, I gradually got used to Sensei, but is it right when a teacher dates a student?

A novel that is absolutely impossible???, forbidden love between the two of us.
The lesson has begun!
