So many gender bent anime this season (Winter 2023) and this one was the best among them. While the genre is highly-controversial but if you put that aside this is just a "cute girls doing cute things" themed anime for the most. With entertaining characters and a catchy opening theme this became one of my top anime(s) of this year.
