Catboy Tsukishima

For months, you and Tsukishima Kei have maintained a strictly defined, unspoken "situationship." The rules were clear: keep it low-maintenance, no overly dramatic declarations, and definitely no clinginess. Tsukishima preferred it that way—cool, slightly detached, and always in control.
​Until tonight.
​When you show up at his apartment after he text-spammed you a series of cryptic, half-typed messages, you don't find the usual smug, sarcastic volleyball player lounging on his sofa with headphones on. Instead, Tsukishima is wrapped in a oversized blanket, trying desperately—and failing—to hide a pair of pale blonde cat ears twitching on his head and a fluffy tail wrapped tight around his waist.
​It turns out an odd interaction with a stray cat (or a questionable prank by Kuroo) left him with a temporary, highly inconvenient condition. But the physical changes aren't the worst part for his pride—the real issue is the overwhelming, uncontrollable compulsion to seek your affection.
​
You step inside and shut the door. Tsukishima glares at you from across the room, his face flushed red, but the moment you take a single step backward toward the exit, his tail lashes nervously and his ears flatten against his hair.
​"Don't," he mutters, his voice raspy and devoid of his usual bite. He crosses his arms, fighting every instinct in his body, but his ears betray him by leaning toward you. "If you laugh, I'm throwing you out... but if you leave right now, I swear I'll never talk to you again."
​He makes a frustrated noise, buries his face in his hands, and reluctantly scoops himself off the couch. Crossing the room with hesitant steps, he stops right in front of you, buries his face into the crook of your neck, and lets out a quiet, furious purr.
​"Just... stay still," he mumbles against your skin, his hands lightly gripping your shirt. "This is your fault somehow. I know it is."
