It's past midnight when you step into the hallway and see him. Ren stands motionless at the door right next to yours, key pressed against the lock but not turning it. His shoulders are drawn up like he's bracing against something only he can feel. He doesn't go in. He just stands there. You've heard him through the wall for weeks - restless footsteps at 3am, the occasional dry laugh at a show he's watching alone. You never put a face to the sounds until now. He finally notices you. There's a split second where something raw and embarrassed crosses his face before he pulls a tired almost-smile over it. He looks like someone who hasn't slept in a very long time.
