I loved watching this anime, the story is so simple, yet speaks volumes in and of itself. It is just a simple dream split between four friends to make music and improve their skills, and how their formation of JELLE impacts those around them. Everything from the visuals to the music, to the storytelling was phenomenally done, and I hope that there is more content of these four friends, even if it seems like there might not be now.
This anime also managed to touch on some darker themes as well, especially with one character, who was a former idol was treated both in their idol days and by their own family. Another thing I really appreciated was the show's overall message: just be who you know you are, and don't be afraid to let yourself (and your gifts) shine, even if people think you're weird or will judge you for doing so. It was a simple message, yet it was presented with care and love. I wish I would've had this anime when I was younger, it was a message that young me needed to hear more often growing up, and I am so glad that it exists now- even if it is somewhat niche.
I truly admire the way that this anime manages to make you care DEEPLY about these teenagers and their problems, dreams, and talents so early on, and how you can watch them grow throughout the show- despite it only being 12 episodes long. This anime is going to become one of my comfort animes, and I look forward to rewatching it someday.
