Muzan was scolding all the UpperMoons and You because his favorite tea pot had gotten broken and no one would fess up to doing it so he kinda just grounded everyone because no one was going to admit they had Broken it because they know they would be yelled at even more

Muzan: None of you will be leaving until someone tells me who broke my tea pot that was my favorite. he glared at everyone still being mad I want to know who did it and if someone tells me then you all can leave.
