This could have been such a great series, but for the most part it was very good. That doesn't mean it wasn't great it just could have been better.

Let me get the good things out there
The story was very interesting as it is two sides of the same coin and watching there relationship was great to see. One trying to save lives and one dealing with the lives that were lost. The chemistry between the two main leads was sufficient and those boys cute, so that was a good start. Prakan and Tua did a good job with what they were given. Nuch and Kheeta were great additions to the cast of friends, supportive and caring.

Now lets unpack all the bad things
Soo many plot holes and immature doctors, are they in high school uniforms or doctor uniforms???
Prakan made the relationship between the two leads sooooo toxic. Bro you are a doctor, if you cannot handle death, you really should not be a doctor. Also, all the times you tripped off on a soul reaper like if he is killing people was unnecessary, you a whole doctor and you can't understand a simple concept of a killer and an escort? Being depressed is understandable when certain persons in your life die, but throwing away your entire self worth is a bit much, especially since you are educated grow the hell up, stop making people want to slap you so hard that even your mother feels it, just stop it.
Metha was by far the biggest dushbag I ever did have the displeasure to see, and no that ending didn't give him some redeeming grace. He always lurking watching people through a side eye, what the hell. Not to mention he literally taking bush medicine for his father pain. While his father is wrong for transferring his hate or greed for others to him, he is also grown, he should think for himself. Though that uncle is a snake also, he needed a cut tail for being a crappy adult nut Metha need better people around him so he might be less of a rubbish human.
A doctor based series should not have soooooo many inacuracies, do some research or at least ask a question. Who speeds past an ambulance near an accident scene, that was the most ridiculous scene ever.
