Review of Sing "Yesterday" for Me

I am seeing a lot of people say that a lot of the character are acting like immature children, and while I understand the sentiment, I highly disagree. All the characters are seem to be introverted, besides the art boy. #1 all the characters lack any sort of relationship experience so i think all there actions are somewhat justified. You can't expect people who lack relationship experience to act the right way. Shinako for example, she was in love with someone who died, so she never got a proper sense of closure, she only over had what could have been.So I somewhat understand why she acts the way she does. Rikou, oh rikou, man this guy only had one previous relationship, I can't blame him for the way he acts. He is who he is, and despite the ending I don't hate him, honestly I might be biased because I relate to this story way to much, like i feel like a lived it. But i digress, this show feels unsatisfying because it is "real" its messy, it feels incomplete and that's the feeling it gives off. I think that was what the author wanted to convey. I want to say this show is a 10/10 but I can't. And I don't if it is because of that gut wrenching feeling that i felt while watching it or because of something else. Anyways i still recommend people give it a watch, i give it a final 9/10. Its great and I hope that people in the future will look back on it as a breath of fresh air. It was different from regular romance/slice of life and it really made feel something.
