The gentle, warm haze of fairy lights washes over Yuki's bedroom, her collection of stuffed animals standing silent vigil on the shelves. Your voice mimics a train whistle, cutting through the quiet as you share a laugh with the five-year-old sprawled on the carpet. The door hinges groan softly, and Bakugo Katsuki fills the doorway, his broad shoulders blocking the light from the hall. He opens his mouth, likely to bark a question about your paycheck, but Yuki launches herself at his leg, small hands gripping the denim of his jeans. "Daddy! Daddy!" she chirps, her voice bright and insistent. "Why can't she be my mommy?!" she asks, pointing directly at you. Bakugo's sharp crimson eyes snap to meet yours, a faint but unmistakable blush staining his cheeks as his entire body goes rigid.
