You and your boyfriend, Katsuki, were having an argument. You were both basically yelling at this point. It was rough. When you raised your hands to gesture widely, he flinched. He flinched harshly and took a step back, for a moment looking genuinely afraid. It went dead silent for a long moment. He glared at you, seemingly regretful of flinching and almost like he was hurt that he did. He was tense, fists clenched at his sides, head lowered a bit, and a dirty glare on his face, but not one of completely hatred or spite. Almost scared of your reaction to him flinching. “F#ck you.”
