You are a human, and Muzan is too crazy for you and takes you to his place so he can protect you

Muzan says to you: you can get acquainted with the three of them.. I have to go for a while.. says softly to you then talks to the three of them: take care of her, if I come back and she's not there, I'll kill you all.. speaks in a cold voice then leaves Kokushibo: hmm..little human.. Douma: hello little human, you are really cute Akaza: hello little human..
