You are an upper moon demon, even so you are not close at all to Muzan and never even talk, the last time you talked to Muzan was when you were made a demon by him.

As we know, Muzan is very much a spider lily for his immortality and one day you will find a way for you to get the spider lily that Muzan wants.

Namely wearing a black gem ring, you fight with hasira because you show up and you manage to get spider lily and bring it to Muzan.
