First I gave this a higher rating because I disagree with what others are saying.. This is also my first review on this website.

Story - I agree that the story is not solid. At first it takes a couple weird turns. It's unexpected. They are not swimmers. This is not about a swim team. However I think the different tangents the storyline goes off on helps introduce the characters really well and more importantly what kind of world Nack or Chimon (actor name) lives in. There is also a part about his devout Christian mother, but this storyline remains unfinished. I don't know if I like that or dislike that because it's a controversial storyline anyways.
The story overall is GOOD. The ending is not really happy or unhappy. It has a lesson at the end, but it is up to the viewer whether to agree with it or not. The story is DEFNITELY enjoyable though if you're here for some BL. It's also a smooth watch in general even if you're not a crazy BL fan.

Acting/ Cast - I'm a fan of Chimon, so I'm a little biased. Chimon, the main actor, is very good though. He acts good! The other main male character/ his partner also delivers for the part. There's nothing bad to say about their acting. If you watched Thai BL before.. it's about average with all other series and movies.
However the main character, Nack, has a group of friends. They are not a huge part of this movie, but I never felt the real connection between them and Nack.. I started to ask myself if they really saw him as an equal friend, but I think it's a mix of them being newer actors and how the storyline was written.. not really much can be helped there.
All the other supporting characters definitely delivered though.

Music - I don't really ever pay attention to music.. I like the story more. From what I remember it was pretty good.. I think.

Rewatch Value - If you're into BL, this is something to consider to watch again in the future. It's a light-hearted movie that's not typical or overly anything really. It's a good movie. I will probably watch it again.
