Granny got some nice sakuga during her dance.

The only thing that stretches disbelief is that they objectively quantify Jinshi as apparently the most attractive being on earth. There's a limit to how detailed and refined a character design can be in an anime, not accounting for taste, so what we get is a... pretty dude that has slightly more feminine facial features than the other men in the show? Its easy enough to hand wave as it is a minor plot point and the story isn't reliant on that being true to life for the viewers, but it is a little jarring when Maomao says things like 'nation toppling' about a simple dance in the moonlight.

The recovery clinic and its surrounding explanations were an interesting bit. Perhaps the presiding non-doctor there might have some use for under the counter meds and Maomao may be getting blackmailed?
