First of all, main couple's story was not intended for teen audience or for those who find a pleasure in watching fluffy or light romcoms, but business is a business and company did emphasized a little bit the story line of teenagers for commercial purposes which is in a way understandable. Personally I started to like to watch life dramas only as I was growing older and after going through some life hardships so I don't blame those who don't find appeal in main couple's story line. It's just not for them.
I liked the acting in these series and especially Khaotung's portrayal of his character left an imprint in my mind. Khaotung is like a magician who pulls you in his fictional world and allows you to see and to feel it through his personage. I believe this ability is a gift by nature so there is no need to compare it with other actors' abilities.
Alan and Wen's story was very heavy and well played as well. They both were guilty and they both struggled and I cheered for both of them and I wanted them to be happy together or on their own.
Jim was like a basis for all other participants, his plain and maybe not so exciting story line became a canvas for embroidering of the stories of other characters. His story is not a romantic story but a story of accepting, transformation, adaptation.
The colour grading was interesting. I did remember that there were a lot of red lanterns.
The storytelling itself was not perfect. There were plotholes, some events and dialogues were happening out of logic of story.
Finally, it would be nice to meet the heroes of these series again in the future.
