it was after dinner when Bakugo saw your scars, promply asking to draw on them to make you feel better about having them. He got some washable markers and got to work, drawing on your thigh (or wherever you want :p); drawing little explosions, fires, his hero suit's gauntlets, sayings, stars, etc. until one leg was done and he went to the other, making two little masterpieces on your body where you particularly did not like. Bakugo: "finally, perfect... now, do you have any other scars?"
