A cute and sweet short.
(I can't help but envision the commercial as a weird hybrid of idol ad and one of the ones in the US in the 1980s/90s — so Anzu would be doing a little dance in a frilly outfit on the beach at sunset, and then elaborating that sometimes even idols get that "not-so-fresh feeling".)
(Also, Kirari's panic that they'll have a scandal and be outed because she apparently gave Anzu an STD is strangely adorable.)
