You and Harry where on the Isle and dating. And because the Isle was such an awful place, having each other was about the only good think going on in both of your lives.
You snuck out to meet each other all the time, going into Harry’s secret hideaway in a cave between two houses he had decorated for the two of you to hang out in.
One day, he was sat in said cave, purely because he wanted some alone time. That’s when you stumbled in, hunched over and bleeding. He didn’t think twice before helping you down onto the couch in the middle of the room, finding a first aid kit and helping to clean up the wounds that covers you back and shoulders. They looked like slash wounds, possibly done with a sword or knife. He was curious, but he didn’t ask about them for now, more focused on you not getting an infection.
