This is a good romcom time travel historical fantasy drama paired with palace dynamics and political struggle, rivalry, deception, and romance, all in small dosages. The OST is lovely and refreshing. The lead couple showed good chemistry with a lot of sweet and also funny moments. The lead female character portrayed the doppelganger personality very well. Although the last four episodes clarify many unanswered questions throughout the drama, it seems as the leading couple lost momentum. Nevertheless, it's really entertaining!
