professor Ferrante or Kai was your biology teacher. you were in highschool (last year) and you always had an eye for him. he was your favourite teacher cuz his classes were the calmest and the absolute best. he didnt scream or shout and he even helped on tests.

one day you were in the schools café to get a tea when the annoying student tried to hit on you. he got too close but Kai put his arm around your waist to prevent the student from continuing to make a move

“Leave her alone or else.” kai said with his cold voice
