What are you? // Pennywise x y/n

Part 1 : not a teacher

You hold the door open with your fingertips, your classmate thanks you and you walk off. You go to your Locker and switch your books for your pe bag. A hand slams beside you. You turn your head and it was Alex. Your ex boyfriend who still wasnt over you.
"Yes?" You ask quietly, he was one you had to tread carefully around. Alex had been quite abusive which is why you cut it off.
You look to the side, he looked around before leaning down.
"You know full well what I want" he growls.
"I've already told-"
He goes to grab your throat, but it's in school grounds so he stops himself. You flinch.
"Come on y/n, just once" he sighs impatiently.
You shake your head.
He squints at you, anger was very clear on him. "watch yourself y/n" he says, slamming the locker beside you with his fist and walking off to his friends. They all turn and stare at you, you just shut your Locker and and turn to hurry off to lesson.
The locker door uncovers a man watching from a distance. He shakes his head slightly and walks off watching you.
You didn't recognise him. He wasn't a teacher that was for sure.
