Disclaimer, I fall in love with the vibes and cast.
even though I've only watched 10 episodes, but there are several points that I will explain:

THE STRENGTH:
1. The film setting is made as close to reality as possible. As Architecture student I related very much. Every lecture scene, architectural assignment to the property is very detailed and relevant. And then, I really like how the workshop scene and the race track are very lively.
2. Amazing (takes) shooting and editing
3. Promising actor, their visual are so great. Sky is the best in terms of acting. his minor expressions are real and not contrived.

THE WEAKNESS:
1. The story line is too simple and lacks new breakthroughs, Just MID. I don't understand why Payu falling in love in the rain scene (earlier episode) How it works? for me it's too random. And I think the kidnapping scene feels in contrast to the whole story line, like jumping too far.
Prapai character is too common: rich, eldest brother, fancy clothes, ask his secretary to delay all the meeting. COMMON.
2. Unnatural voice call effect that hard to listen

MY DEEPEST OPINION: SKY-PRAPAI > RAIN-PAYU (Story)
I actually prefer the story line and acting style of Sky and Prapai. There is a little bit strong element to their relationship, at least not as overwhelming as Payu-Rain story . And Prapai's voice reminds me of Bright from Together the series. What a Handsome voice.

Yah.. 7,5 for me at all.
