I just completed this drama. It was spectacular. Were there any plot twists? not really. Was it a wonderful drama? Hell yes.
I know nothing about the weather and need to state that at some points in the show i was very lost as to what was being said at first but it is just like the real world. I know nothing about predicting the weather and that being said i rarely watch the weather news but after this i think ill need to.
The concept of this drama is not particularly new. Sort of reminds me of MER or Code blue in the sense that SDM is a new organization and it is still in it's trial period.
I dont think there is a scene which was draggy. I felt emotion from each character in every instance.
I honestly think that this drama showed real world weather problems and also the humans who insure the safety of a country prone to natural disasters and work in the background.

I love that there was no "Villan" and there was no "dumb" characters. Most importantly there were no arguments between characters. Just a blunt man and his colleagues who will prioritize the safety of people during natural disasters using meteorology as a way to do so. I hope this gets renewed but even if it doesnt im happy that this drama was made.
