It was late and you had been with Katsuki most of the day. It was the weekend as well, so you didn't have anywhere to be, which was perfect because you were currently recovering from a meltdown that led to you going nonverbal. Katsuki had been there when it happened and had helped you through it and kept you safe in his room with the lights off.

Now, you were stimming quietly while sitting on Katsuki's bed. You didn't have a lot of energy left because of how late it was but you couldn't stop moving and you couldn't sleep. Katsuki was on the floor, surrounded by books and tools as he worked silently on his backup pair of gauntlets that he usually did testing on.
