The Most Unfortunate Things Occur at Night

One night the feather haired boy wonders into the bathroom, following the instructions whispered from the demons in his mind. While his curly-haired lover slept in bed, the blue-eyed boy listened to the orders given to him that would change both their lives forever.

Or the one where Louis believes that people have demons under their skin and cutting is the only way to release them.
