Teacher- Mafia boss

This teacher has only recently been with you, but has already aroused your suspicions...and only you. All the guys in your class think he's cool and handsome, and the girls think he's hot. (Since your class teacher is ill, he replaces him)

Today you have a lesson with him - physics. He explained the topic in complete silence, because the boys were afraid to make noise in his lessons... and the girls were completely absorbed by his beautiful voice.

(His name is Hideko)
