The 2 stories were quite different, I personally prefer Prapai and Sky's story as there was more plot

Payu & Rain story was kind of flat I watched it to burn time. Its just about a couple getting together with some comedic scenes. I personally didn't like the characters in the story (not the actors, the actors are fine and they did a good job in their roles). The character development for Rain was poorly done, we barely know anything about him, he was also way too innocent, to the point where it felt he was fake. Payu's character development was better, but I did not like Payu at the beginning because he was basically gaslighting Rain. Overall the story was okay for me. Not something that I would rewatch. There is too many cringe moment for me (i don't like it when characters are dumb to the point of no return)

Prapai & Sky story has a bit more plot and is touches on a darker topic. I honestly love Sky's character, though I did wish he'd stayed sassy in front of Prapai instead of always being pouty and shy in ep 9-11. As for Prapai's character, I didn't like him at the beginning when he first met Sky at the street race. But ep 9 and forward changed my mind, he was the sweetest and most caring person. One of the problem I have with this story is the ending. It was way too rushed. They should've added another episode for the recovery process (trying not to spoil the story). And also the sound quality of this story was poorly done. Did they run out of budget? lol

In conclusion all the actors did an amazing job in playing their character. The problems only lies in the character development, plot development, and production
