The tap of nails against his door stirred him from the lack of thoughts he was currently entertaining. He didn't call out that he'd be there in a moment, instead unknotting the towel from around his hips, exchanging it for a pair of loose-fitting grey pants that hung on narrow hips, barely holding on.
This was how he answered the door, a crack into the hallway to verify the person on the other side before it opened wide. Skin was still damp from the shower, hair darkened with water, but he stepped aside to let him in, the door closed tight behind him, locks turned, barring the world from entering unasked.
