Fix You (Larry Stylinson AU)

"Why do you do it?" Harry gives him a puzzled look.

"Do what?"

"Cut yourself." Harry takes a moment to give him an answer. His face flashes with several emotions like he doesn't know what to say.

"The same reason you drink so much, to numb reality."

Or the one where Louis is an alcoholic professor. Harry is his quiet yet beautiful student who never wears short sleeves. This is their journey of learning to love themselves and maybe along the way, each other.
