This drama consists in two different parts telling the story of two different couples.
The first one is so cringe I felt it down my skin. The actors are not to blame, but the no-sense dialogues, the cringey lines. Rain is such a kid, he's basically the classic bimbo waiting for a daddy to take care of him. And I HATED that. Sometimes he says stuff - mostly sexual innuendos - that are just too cringey to be true (ex. ep 7 where he says "P' Payu is the only one who can screw me" to the one who just kidnapped him). Let's not forget the "punishment" scene where Payu smacked Rain's butt: no, it was not anything bdsm, they were not in any kind of relationship, they were basically strangers. What's wrong with the author? That's called assault.
I don't even know what kept me from dopping this - maybe the chemistry was good enough to save the almost-whole thing.

I enjoyed the second part the most. We still have the chasing-concept (almost stalking at some point), but we can see the effort Pai put in gaining Sky's trust. Their relationship started in the most toxic way, but it ended up with a clamorous character development from both sides and I enjoyed it the most. We can see how Pai cares a lot about Sky, how he really wants to take care of him despite his first intention to just get laid with him. And I really enjoyed that. The actors did a great job.
Still, the flaws were in the script. I mean. Sky's trauma is showed just when necessary to create some drama. You shouldn't talk about sexual assault if you're going to take that easily - this was troublesome.
Another HUGE problem of this latest part is the sound problem: music sometimes is louder than the dialogues, the phone-calls are just cringe when you can hear the voice on the phone LOUDER than the voice of the actor on the screen.

In the end, what I'll remember dearly of this drama is Pai's smile. That is the cutest.
