I know many people like this drama but it just didn't fall right for me, may be I was expecting a lot! idk.. I watched this after Kairos and Kairos was better for me, I didn't like the romance part of the drama, and actually it was annoying.. Would've been better with out the romance aspect..
I really hate dramas with open-ends.. I've started this drama after Kairos and I feel like the story progression was kinda slow, there was so many unnecessary and prolonged scenes and so many flashbacks .. This gave me Dark vibes tho this drama was made before Dark but none of my questions were answered by the end of this drama.. The only question got answered is " Why this is happening?" which was okay tho it wasn't very satisfying, but none of these questions where answered, " When did this loop begin" " Why Park Hae Young?" I thought this will be very promising but like always, THE ENDINGS! it's always the endings... It's always gonna be that open endings.. Korean writers should start writing the ending before the story itself cause this is ridiculous
