Overall: this could have been a 9 or higher if they had made things more clear.

What I Liked
- the sci fi/future aesthetics
- the actors did a good job
- making viewers think about differences between gender, sex and sexual orientation, I find this graphic useful https://au.reachout.com/articles/the-difference-between-gender-sex-and-sexuality

Room For Improvement
- things were just a little too open/not clearly stated, for example, Yi An asks Zhou Yang Kai if he'd like Yi An to be a woman but Zhou Yang Kai doesn't actually respond clearly either way. The ending is fairly open as well, I guess we can infer Yi An's choice but showing Yi An making the selection would have been good so viewers were clear about the decision.
