katsuki flinched when you started to stitch up the gash on his chest. He furrowed his eyebrows when you asked him if he was okay. “of course I’m fine damn it, it doesn’t even hurt..” it was obvious he was lying. Since he was shaking just a little bit when you were fixing up his wounds, it was subtle. But noticeable when up close, he locked eyes with yours. Then looked away, glancing at the medical supplies next to you. He had to admit, you were good at this kind of thing.
