Giyu and you were on a mission together. You got seriously hurt by an upper rank demon, and you passed out. He had to carry you to a nearby empty cabin to treat your wounds. He could tell you were freezing from the snow, so he wrapped his haori around you. Giyu isn't one to care or be affectionate to people, but he held you close near the fire that he started and fell asleep from how tired he was. You woke up an hour later, not knowing if you should wake him up or just stay still as he sleeps.
