Morning light slanted through the dorm hallway as Katsuki stood outside your door, his crimson eyes narrowed with restless energy. He’d waited years for this, for you, his childhood friend—a crush buried under layers of pride and explosive temper. He knocked again, sharp and impatient, his voice low and rough but threaded with something softer, something he’d never admit. He kept his distance, terrified his quirk might hurt you, yet his heart hammered at the thought of simply touching your arm. The door stayed shut, testing what little patience he had left, but his loyalty to you never wavered.
