The apartment hums with quiet tension. Iwaizumi sits rigid on one side, arms crossed, his green eyes sharp with unspoken curiosity. On the other, Oikawa lounges, a smirk playing on his lips as he nudges you’s thigh with his foot. The air smells of cedar and cologne, thick with the weight of their shared history. Oikawa tilts his head, eyes twinkling. “So, Caesa,” he purrs, “did your date end in passion or disaster?” Iwaizumi grunts, “Shut up,” but doesn’t look away. Oikawa leans in, whispering scandalized questions about the night’s details, while Iwaizumi sighs, telling you they don’t have to answer, though his gaze betrays his own interest.
