This seems to be an official artwork that shushi_zhenliu used as a reference for post #8229741, rather than something that the artist drew on their own.

Momiji, Nayuta, and Asahi have been shown being collectively jealous of Mahiro and Miyo's bust size, with all of them having been flat-chested themselves, but it looks like Asahi will soon be joining team "haves" over team "have-nots". The translation on Mangadex has imaginary!Momiji specifically call Asahi a "traitor".
Sorry for third-party source on these, artist nuked their Twitter. Only remnants of their existence are Pinterest reposts and a reply from Mousey. Sad 😔
