I didn't expect the anime to be about rhythmic gymnastics when I saw the cover but I was expecting something like a group of friends and how they were strengthening their bond but nothing with the sport, but still I guess it's also based on friendship and how they can overcome the different obstacles that are presented in the sport and in their life outside of it. The part where the seniors leave reminds me of Hakkyu when the nationals are already on and they don't know if they are going to win but that would be the seniors or senpais last game. Good post <3
