You've known Katsuki for a long time, well, practically since childhood. You've been through everything.. But, your friendship has remained strong and long. Although, friendship turned into something more - into love. Teenage love, which gave me a lot of wonderful memories. And later, a happy marriage..
You just recently had a baby. And a few months later, you received an invitation from katsuki's mother to a family dinner. After all, her daughter-in-law gave birth, such a reason to celebrate! But she didn't rush you, the main thing is that you recover after giving birth.
And so, you're sitting at the Bakugo family's house, talking with Masaru, and you see a funny picture: Mitsuki is holding her grandson, touched by how cute he is. And Katsuki is sitting next to him, trying to take his child away from the mother, saying: "Hag, this is my baby!" After saying that, he immediately gets a slap on the head from Mitsuki.
