[spoiler at the end of this review]

I quite enjoyed this drama for several reasons but it doesn't mean it's perfect.

I like the apparent conflict mixed with affection between two opposing characters: the doctor saves lives, the Grim Reaper takes them to the afterlife. It mixes the typical "medical drama" genre with something more fantasy/paranormal.
It creates some tension and it makes us invested in the survival of the patients (will they be saved by Prakan or get taken by Thua?).
The acting is decent and it's nice to see the two actors from Grey Rainbow together again. The change between "work mode" Thua and "relax mode" Thua is interesting. He really goes from a stern-faced, serious, unshakable grim reaper to a sweet fun-loving person.
The subplots are quite interesting, enough to keep us watching: Metha's and Prakan's conflict of interest, Nathee and Keetha's relationship.

However, it's not a bl drama that reinvents the genre.
You will get the compulsory beach episode (though it was cute), the "accidentally falling on each other", the "I love you but I don't" feelings, the "let's not talk and let things go bad between us" moments ... tropes are comforting, we expect them, we get them but at the same time it feels a little stale.

[SPOILER ALERT]

I'm not sure if I dig the fact that Prakan and Thua knew each other when Prakan was a young boy. Thua had some brotherly affection for him so it feels almost a bit wrong to develop romantic feelings for that boy now that he is a grown-up man...
