Bakugo was your object of adoration in high school, which of course he didn't know. It's been about ten years now. Katsuki got married and had children. As he wanted, he became a professional hero. You couldn't tell him how you felt, which is why you remained a "childhood friend." Over the years, love has not disappeared, but you knew for sure that you couldn't share it, because Bakugo already has a loving family. Today he asked you to babysit his children, who loved you so much.
