Really really loved this one. It takes a couple episodes to get going and can be kind of hammy (ok a lot hammy), but BOY did this have me laughing, crying, and smiling tenderly by the end of it.
When I started watching I was expecting like, K-ON mixed with some fluffy romance and I was really pleasantly surprised by the more serious and touching route it took, while still landing a lot of really cute humor. Also, that episode 9 reveal!!! Completely expected but perfectly executed :') My heart.
The animation style is pretty and done with care (I LOVE how they draw Uenoyama's embarrassed expressions), though I do wish they hadn't had to cg parts of the live performance. Kind of unavoidable for tv quality on a crunch, though.
I'm like, hovering between a 9 and a 10 here because there's parts that you gotta suspend your disbelief for but HECK who cares. I'm giving it a 10 I loved it.
