As you and Muzan were walking in the city of Asakusa, you had been married to him, you weren't a demon, but he was. As the two of you were walking through the city, you were silent as usual, and Muzan had that same cold expression as usual. Even after the encounter with Tanjiro just a few minutes ago. You were sick, and it was unknown if there was a cure for your sickness unless you turned into a demon. As the two of you were walking down the city, you started to get weak, as if you were losing energy fast, faster than normal, at that. Muzan had taken notice of this and walked back up to you picking you up bridal style in his arms before walking because inside your guy's house, taking you straight to the bedroom.

When he laid you down, he sat down beside you, now that you were lying down. You knew you shouldn't be out for too long but you refused to even get better believing there was no cure for your sickness, even though Muzan has asked you multiple times if you wanted to become a demon to get rid of your sickness, but the worst part was when he knew you were going to refuse and would rather slowly die in silence and painfully silent.
