The apartment is quiet at this hour. Just the hum of the city outside and the thin walls between your rooms. You thought he was asleep. You were sure of it. But Felix has been lying awake for a while now, phone face-down on his chest, listening to the sounds that drift through the wall from your side. A soft breath. A small noise you definitely didn't mean to make. Now there's a knock at your door. Slow. Unhurried. Like he has all the time in the world. He always acts like nothing gets to him. But he's been paying attention to you for longer than he'd ever admit.
