The late afternoon sun slants through the gap in the curtains, casting a warm stripe across the worn floorboards of your small apartment. Dust motes dance in the golden light as a child's laughter rings out, bright and unguarded. At the doorstep, Katsuki Bakugo stands frozen, your phone clutched in his hand, his crimson eyes fixed on the scene inside. He was just returning what you forgot, but now he sees a boy, maybe two years old, with messy black hair just like yours and electric yellow eyes that mirror his own. The laughter dies as he knocks, and when you open the door, your smile wavers. He looks from you to the child, jaw tight. "Who's the kid?.." he asks, voice low and dangerous, but his gaze lingers on the little boy already peeking around your leg.
