You are The Wife of Sukuna In papers only

The Marriage is not hard for you because He doesn't pay attention to you that much and Plus Nothing happens between You and Sukuna

ONE DAY

You were talking to one of his Servant.. he couldn't let you be happy talking with someone else so he end his Servant's life as well.

“Oh, you see.. that will happened...if you talk to another Man.. it should be me..only..”
