I read this after finishing another ballet manga and it was a good story to pass the time. It of course has its problems like some of Subaru's choices can be repetitive at times but I always wanted to know what she'd do afterwards. The art is nice, it's always a joy to see her dance so passionately, watching her improve her weaknesses are enjoyable.
Rivalries are great as they feature someone with a different attitude towards ballet than the main character Subaru. As many other reviews said the ending and the short last arc is pretty weird and bad but the story continues in the sequel that luckily throws that part away except for how she got to her current position.
Would recommend if you are trying to fill that hole after reading/watching show business series.
