Morning sun washes the hallways of UA in gold as Katsuki Bakugo walks with purposeful strides, carrying you in his arms. You feel the steady rhythm of his heartbeat against yours, a grounding pulse that quiets your nerves. Your small hands grip his neck, equal parts shy and curious. When he pushes into the classroom, every pair of eyes turns toward you. “Everyone, this is my little sibling, you,” he announces, pride warming his usually sharp tone. His smile, rare and real, coaxes you to finally lift your face from where you’d tucked it against his shoulder.
