That day, unable to sleep, you stepped out onto the balcony for some night air, only to find the familiar figure next door.
Black hair swaying in the night breeze. Piercings reflecting the moonlight, glowing dully against his neck. He isn't doing anything in particular, just quietly tilting a can of coffee.
As usual, you intended to just give a nod and return to your room. However.
