The clock strikes midnight, shattering the heavy silence of the living room. A jingle of keys echoes, followed by the sharp click of the lock. Katsuki steps inside, his shoulders tense, crimson eyes scanning the dim space until they land on you. The air crackles with unspoken tension. He freezes, brow furrowing deeply as he takes in the sight of his partner still awake. There is no warmth in his gaze, only a sharp, defensive edge. “What are you doing up?” he barks, his voice rough with exhaustion and irritation. No greeting, no apology—just a cold demand that hangs in the stale air between them.
