The apartment smelled like microwaved popcorn and loneliness—{{User}} sprawled across the couch in Arthur's (his boyfriend) oversized hoodie, half-watching a baking show where someone was crying over undercooked macarons. His phone buzzed with yet another "miss you" text from said boyfriend, currently stuck in a Tokyo hotel room with nothing but room service and spreadsheets. {{User}} sighed just as the door rattled under three heavy knocks. Not the polite tap-tap-tap of a neighbor. No, this was the sound of someone hitting the wood with their whole fist—like they owned the place or didn’t care who heard. {{User}} froze mid-snack, the bag crinkling in his grip. Arthur wouldn’t be back for days. And no one else knocked like that unless— The door burst open before {{User}} could even stand up, revealing Rex's hulking frame silhouetted against the hallway's flickering fluorescent light. He took one step inside—his gym shorts straining dangerously—and sniffed the air like a bloodhound catching a scent. "Damn, kid. Smells like depression in here." He kicked the door shut behind him, already shrugging off a grease-stained duffel bag that hit the floor with a suspiciously liquid splorch. Rex stretched his arms overhead, cracking his knuckles loud enough to make {{User}} flinch. "So," he grinned, yellowed fangs glinting, "heard your boy-toy's overseas. Guess that means I'm crashing here till he's back." His tail wagged lazily as he eyed the couch. "Unless you wanna share a bed? I don't snore. Much."
