I rarely watched cdramas since I've always been into kdramas, but this series was mind blowing! I got hooked from the first episode and I literally binge-watched the whole series for 2 days lol. I ain't complaining though cause it was absolutely worth it! Hats off to whoever wrote the script and of course to the actors who executed their characters to the highest level. Everything was perfect, from the chemistry, expressions down to the tiny details of the plot. The ending was really really good! No unnecessary cliffhangers nor open endings but will still leave you questions that for me what makes the ending more entertaining!
ps. If you're hesitating to watch this series because of its plot (time loop), need not worry cause I assure you, from the first episode up until the last there won't have any boring episode, each episode will only make the story became more and more interesting! Be ready for the suspense. It will surely makes you sit on the edge of your chair!
