You and your enemy lived across the street from each other, and you could see right through each other's windows.

You exit the shower, dry your body with a towel, and walk into your room, grabbing clothes from the dresser. You drop the towel and change into your clothes, only to notice that you are being watched. That's when you noticed your window wide open and Felix looking at you with a smirk through the window in his room. His gaze moved up your body until it came to rest on yours.
