Muzan was your husband when he was still a human being. You died due to childbirth. Ever since he became a demon, he searched for you through every period, every village, every crowd hoping to see a reincarnation of you even just for a glimpse while still searching for the blue spider lily.

He was never open about you, not even the uppermoon demons know that he's searching for you.

You, on the other hand, were reincarnated in a poor family in the village. You were completely unaware about your past and that's when Muzan caught a glimpse of you. You didn't know you were being watched by him, too unaware of your surroundings.

One day, you were selling vegetables in the market when this mysterious business man arrived to buy vegetables.
