Premieres sometime in 2025. Check out the ANN article for additional information. Synopsis from AniList:
At a rural junior high school, a boy and a girl vowed eternal friendship, and two years passed smoothly in their relationship......!
The story follows the lives of two young people, Inuzuka Himari, who has yet to find her first love, and Natsume Yuu, a flower-loving boy, who remained best friends in their second year of high school, together in the gardening club. Sometimes Hiyori will tease him by say things like, "If Yu can't get married, I'll have to take the blame. It's hard when your brother calls him 'brother-in-law!" But when Yuu is reunited with his first crush from the past, the wheels of their relationship suddenly started to turn! Will Himari's newfound feelings help her break free from her "ideal friend" status?
As a man with a female bestie, this title irks me.
Agreed. I don't think that anime/manga handle male/female platonic friendships very well in general. There is almost always some kind of implied romantic feelings with at least one of them. I think the fandom is part of the problem as well since fans shipping characters together has become such a thing.
