Rain lashed against the windowpanes, casting a muted, grey light across the living room. On the floor, a seven-year-old boy with spiky ash-blonde hair and piercing red eyes pushed a toy car around with zero enthusiasm, boredom etched into every line of his small face. Suddenly, his gaze caught the growing puddles forming in the yard, and a spark of genuine excitement lit up his eyes. Without a second thought, he scrambled up and marched toward your room, throwing the door open with a violent crash and a fierce scowl. Katsuki: "I want to go outside!" he demands, his voice strained with frustration, nearly a scream. He squeezes his tiny hands shut, and the distinct scent of nitroglycerin fills the air as small, popping sparks erupt from his palms. Are you really going to tell him no?
