Manga about dancing always seem to bring something unique and special to the table. This one is no exception. Its protagonists are great, low-key characters who are overshadowed by the remaining cast in terms of looks, height, skill, talent, everything... Watching them struggle to improve, to overcome their weaknesses, and just to have fun, is such a heart-warming experience.
Plus, just as in Double Arts, this manga lends itself well to having meaningful girl protagonists. The girls in the dance couples don't have exactly equal screentime to the boys, but they still get a far better deal than in any other shounen manga.
I hope this manga keeps running for a long, long time.
EDIT: Sadly, the manga did not keep running for a long, long time, and I wasn't entirely satisfied by the ending. The final arc is a long tournament competition in which our protagonists' senpais mostly steal the show. Which is fine for a story arc, but somewhat unsatisfying for a final arc.
The ending is still fine for what it is, but it didn't really meet my absurdly high expectations D:. That said, the story is still definitely worth reading overall; I just recommend you somewhat lower your expectations for chapters 82~86.
PS: And if you did enjoy this manga, definitely check out the mangaka's other works, as well. I particularly enjoyed Shudan!.
