Premieres sometime in 2026. The new PV is here. Check out the ANN article for additional information. Synopsis of the source manga from AniList:
Gorou is a gynecologist and idol fan who’s in shock after his favorite star, Ai, announces an impromptu hiatus. Little does Gorou realize that he’s about to forge a bond with her that defies all common sense! Lies are an idol’s weapon!
After the disappointing ending of the manga, I just lost all interest in the anime too. Really hoping they take some creative liberties and rewrite that ending, but I know I’m just coping.
