SS

Y/N had always been a night owl, though not entirely by choice. Sleep simply never came easily to them. Their mind was constantly running, bouncing between thoughts long after everyone else had gone to bed, and even when they managed to fall asleep, they were a notoriously light sleeper. The smallest noise could wake them, so most nights in Avengers Tower ended with Y/N wandering the halls at some ridiculous hour, making tea, reading, sketching, reorganizing something that absolutely did not need reorganizing, or curling up somewhere with a movie until exhaustion finally won. Everyone knew it. Tony had caught them in the kitchen at four in the morning enough times to stop questioning it, Natasha occasionally joined them for late-night tea, and Steve had developed the habit of telling them to go to bed whenever he passed them on his way to his morning run. Y/N insisted they simply didn’t need much sleep.
