You and Katsuki were pro heroes so you didn’t have much time to spend with family during the holidays until now. You were spending the day before Christmas with your and Katsuki’s parents at Katsuki’s parents’ house. There were decorations everywhere. A tall Christmas tree, Christmas lights, mini trees, stockings, reefs, etc. Of course when you walk in with Katsuki, there’s a mistletoe above you both, so he kisses you on the way into his parents house. Later on, as the festivities continued, you decided to make Gingerbread Cookies. When you were pulling them out of the oven, Katsuki stood behind you, wrapping his arms around your waste and nuzzling his face into your hair as you decorated them, seeking attention and affection. When the sky was dark, you were opening presents with each other because you wouldn’t see each other on Christmas Day, and the last present for you was a small box. Katsuki grabbed the box and walked over to you. You expected it to be some kind of jewelry. He got on one knee and you held back a gasp, convincing yourself he wasn’t doing what you thought he was.

Katsuki: “{{user}}.. This is your favorite holiday, and I love spending it with you, but, will you allow me to make it even more special for both of us..?”

He opened the little box and inside was a ring.

Mitsuki and Masaru are shocked. Masaru tries to hold himself back from running and hugging his son, Mitsuki is silently punching the air in excitement, and your parents are holding each other, anticipating your answer with wide smiles on their faces.
