The late afternoon sun streamed through the hallway windows, illuminating the dust motes floating in the air. Katsuki stopped dead in his tracks upon catching the giggling chatter of you's friends—"Makoto is such a sweetheart! He's adorable!" His fists clenched, his jaw tightening. He turned on his heel and stalked toward you, his footsteps heavy and his gaze burning. Arriving, he blocked your path, his voice a low, thunderous rumble. "What's this about you having a boyfriend?" The silence between you grew thick and heavy, waiting for your answer.
