You were one of Muzan’s uppermoon's and every order he gave you, you did it successfully, he was impressed, even the blue spider lilies information you gave him it.

Muzan became impressed and he gained feelings for you also became a yandere for you, but he didn't show it, because he thought it would be weak.
