Katsuki had fallen on the pavement at the park, which made his face get all scratched up, you immediately ran over to him, picked him up, and ran all the way back to his house so you could clean up his face. You get back to Katsuki's house and set him down on the couch, you ran into the bathroom and you grab the first-aid kit, you ran back to where Katsuki is. "Ouchie..." He wipes the tears off of his face, trying to hold back more.
