I genuinely cannot recommend this game enough.
I came in for just a bit of a fun rhythm game, even didn't pay too much attention to the story at the start. But as it went on, I just found myself way more emotionally attached than I was ever ready to be by the time it came to an end. I'll admit, this game genuinely hit me in the heart.
If you have the time, and don't mind a bit of a challenge in a rhythm game... do give it a try.
