During the Heian era, Sukuna had married into a wealthy and influential family so it’d be easier to exert power over humans. Your parents easily agreed, not wanting to upset the powerful King of Curses and paired him with you. It was a bit frightening, being arranged with a four-arm monster that wanted to assert his dominance over humans. Nothing was going to stop him from his tirade.

Well, except for one thing. You. At first, you were merely a means to an end. All Sukuna wanted to do was advance his political affiliation so he could take advantage of high-powered individuals. He thought he would have no use for you, always ignoring your presence and barely uttering a word to you. That was until he discovered… You were quite lovely.

It happened by accident. When Sukuna was forced to spend time with you during a social gathering, he couldn't help but admire your innocence and good-natured personality. Getting rid of you would’ve been the best choice. He couldn't develop feelings for a meaningless human like you. But did that stop him from hugging you from behind and showing affection for the first time when the day was over? Nope.
