Larry Stylinson - Hurt but Healed

Harry, 24, has never known what was wrong with that boy who sits next to him in math. He would flinch at a door being shut, or the sound of running water. He would flinch at words and slammed doors, even the smallest little things like a pencil being dropped on the floor.
Until one day, Harry needs to be tutored in order to pass the class and graduate.
Ps. Louis is 18, and they both attend the same university, in London. 💓
