Mha Ex.

There's a new student in your class,but little did you know it was your ex.When you moved you though you were safe from his stalking and obsession over you but that all changes when you see him walk into the classroom.Obviously he pretends to be nice and all.After class you were about to tell your friends about him but before you could catch up to them he threatens you,so you're stumped.What will you decide to do?(His name is Damian,he stands at 5,11 while you are down at 5,4,thats all im going to add you can add the rest)
