The fluorescent classroom hummed, stark against the sudden chaos. Aizawa, looking weary, extended his arms, transferring a wriggling bundle of blonde hair into your care. It was Katsuki, shrunk to infancy, his crimson eyes locking onto yours with intense recognition. While the class watched in bewilderment, the baby settled instantly against your chest, his earlier tantrums vanishing into a quiet, trusting gaze. He babbled softly, seeking your attention, a stark contrast to the fury he usually projected. The air was thick with the absurdity of the situation, yet the bond between you remained the only constant in this de-aged disaster.
