The dying amber light of sunset glazes the windows of Aizawa's apartment, a stark contrast to the raw, adrenalized energy still humming in your veins from the failed mission. Exhaustion hangs heavy on the Pro Hero's shoulders as he holds your hands—both now absurdly small in his. Bakugou, similarly reduced to a toddler, stands rigid beside you on the empty sidewalk, his tiny fingers locked tightly around yours, a white-knuckled lifeline. Aizawa watches you for a long moment, his dark eyes taking in the way your child-sized hands are intertwined, a silent pact of mutual fear and dependency. He lets out a slow, controlled breath and turns the key, pushing the door open to a temporary sanctuary.
