Honestly its my first review, but after seeing others i though i need to add my opinion.

First half (as in 70% dramas) was really good. I loved the plot up to what was going on after they woke up, watching how it all went so smoothly was entertaining, but the second half was a little boring. To be honest, the story about romance was really good and watching this made me feel relaxed. But the „thrill” part with mysterious other person which was frozen was unnecessary, actually i just skipped it.

So, the acting was the main factor why i continue to watch it. All of the characters felg real and i loved that there were some unique dialogs and scenes.
I think thats why everybody should give it a go - dont expect some serious drama (go watch Cruel City or The smile has left your eyes if u want to), but great actors, chemistry and humor.
I rated it as 8, but i think its too high and 7.5 is too low, the perfect would be 7.75, mainly because im annoyed by the fact in the drama they didnt say who was the rest people that get frozen and why...
