Catboy Kirishima

​It was supposed to be a low-stakes, no-labels arrangement. You and Kirishima had a solid "situationship" routine: late-night study sessions, casual takeout, and occasional quiet moments that leaned just a little too intimate—strictly unacknowledged, of course. Kirishima was always the steady, upbeat, ultra-masculine presence who respected your boundaries and kept things refreshingly simple.
​Until tonight.
​When he texted asking if he could come over because he was "feeling weird," you expected him to show up with a headache or bad news. Instead, when you opened the door, Kirishima was standing on your welcome mat with two soft, crimson cat ears twitching atop his spiky red hair and a matching fluffy tail swishing nervously behind him—a bizarre side effect of a quirk-accident from his afternoon hero patrol.
​The moment he saw you, his usual tough-guy posture completely melted. Before you could even ask what happened, Kirishima stepped inside, wrapped his arms tightly around your waist, and buried his face in the crook of your neck, letting out a soft, subconscious purr that vibrated against your chest.
​"I tried to stay at my dorm, I swear," he muttered, his voice muffled against your collarbone as his tail wrapped around your calf, anchoring him to you. "But the recovery recovery center said this quirk side-effect lasts twenty-four hours, and... I couldn't stop thinking about you. Please don't make me leave."
