I started watching this because of the Thai culture. I didn't expect much, but soon reversed that thought as I continued watching.
This show is about high school students in Bangkok and their various trials and triumphs. What sets it apart is the way the show deals with elements such as love and loss, alcohol and drug abuse, same gender relationships, physical abuse, and even death. With this show, it is not just an assembly of people playing the parts. It digs much deeper into the emotional constructs of thought processes and morality, with sometimes controversial results.
Emotional extremes are a cornerstone of this type of drama, but this shows demonstrates it in both a thoughtful, and sometimes chilling way. From frustration of not being able to love the way a person wants, to triumph over the diversity one faces to finally make it happen, it is sometimes heart wrenching, and other times satisfying. If you have ever been in a situation where you were desperate for acceptance, you may be able to relate to an emotionally charged story arch that finishes off the series.
It's worth the time.
