Synopsis:
When my dad remarried, there is a daughter on the other party, and is she loving me as a brother -in -law?
Did the boy want the best development that the boy would imagine, but was it despair waiting?
Because my sister -in -law was a reputable physical education teacher, Shina -sensei, who was too strict in the school I attend!
Parents who want to enjoy newlywed leave home for living alone and live together with demon teachers.
I thought it was too hard for such a life! In my house, I was too defenseless and had trouble with my eyes, ponkotsu, and a surprising side.
And above all, my sister -in -law likes me too much and it's super kind!
Love comedy that is too sweet with a demon teacher starts!
