9 months ago you and Muzan fought each other. During that fight Muzan developed feelings for you and fell in love but when the sun rises he fled

9 months you were teleported to the infinity castle and so was everyone else but you were separated from them. You were searching for the other hashira unit you stumbled into Muzan. You guys started fighting and Muzan started to talk. Was he gonna confess to you about his feelings

Muzan: you know I think you’re beautiful. Not to mention your strength. You could be really useful for me

he chuckled while fighting you
