The opinion I have about this series is that the initial ideas were quite light, but the actual execution and character development later on made it enjoyable. At the beginning of the manga, the main foundation is pretty much set. The main character, nicknamed "Pochi," had been made fun of for his voice and would refuse to speak at school as a result. However, a member of an all-girls band, Ageha, heard his voice and saw something special in it, and wanted him to be the vocalist of her band "Sora". However, she made him crossdress and hide that he was a guy to theother members.

The panels and dialogue were clean, and the art style wasn't insane or anything, but it was cute and fairly well done.

From the premise alone, it sounds like a lighthearted comedy, which was the case initially. The latter half of the manga started taking a turn for more drama, and some more backstory on Ageha.
I do appreciate that the story strayed a little from the start, focusing more on the actual band, though the struggles depicted were brief. In terms of the moments themselves, Ageha's and Pochi's backstories and the band's moments weren't particularly special or stood out. The author tried doing comedy but tried bleeding in deeper moments. You can tell the author didn't plan much of it initially and tried to wing it. However, the ending itself wrapped up pretty smoothly; they ended up really tying it up nicely despite those small issues.

The aspect that stood out most was Ageha's character development, how she developed a stronger sense of music when she went overseas, and worked through her fears at the end, although both were brief. The other band members, outside of Pochi and Ageha, are completely flat in writing. Although many of the side characters weren't very developed, I found them to have more personality than the main characters. Michael Gabriel, the old grandma in New York, the guy who became a superfan of Sora, and the guitarist of the band that Ageha admired had more personality than the rest.
