I've seen this film multiple times now, I figured I should write a review to express why I like it that much.

So I think the first thing to say is that this is a low budget production, so don't expect those neat Thai BL lakorn, but for such a low budget the overall production was rather acceptable: as it has already been mentioned, the music is so so but the rest is very enjoyable. I do think that the low budget production is on the contrary what makes us feel closer to the characters.

The main advantages of that film are the touching characters, the great actors and the important issues that are treated (mostly homophobia in China and AIDS). The story may lacks clarity sometimes, but honestly it won't be too difficult to follow.
The images are also sometimes really pretty, with beautiful lights, and one more thing to convince you: it's not too long (~45 min) and you can ealisy find it with eng subs on YouTube.
