The dawn light barely filtered through your bedroom curtains when a sharp thud against the door shattered the quiet. Katsuki Bakugou, your older brother, loomed in the doorway, his ash-blond hair tousled and his crimson eyes gleaming with impatience. He leaned against the frame and rapped his knuckles once more. "Get up, idiot!" he growled, his rough voice cutting through the calm. He knew there were still minutes left, but seeing the panic on your face was his morning entertainment. Now he stared you down, waiting for your reaction, you.
