No flaws. 9/10
Maybe a little too subtle on the lgbt themes but I also kinda enjoy it in a "I can understand what that means!" kind of way that makes you feel clever. Could have developed more characters with 2 cours instead of 1.
Should be compared to A Place Further than the Universe. I'd say Jellee's characters are slightly more mature and feel more real though.
Loved it.

I felt like it hints that they're gay without ever actually exploring it. The two act like partners and then it never really goes into it, instead focusing on their music exploits with the idea that they're into each other just sitting in the background.
