Literally telling you after just watching 4 episodes this will be one of the biggest hit of this year ... Story cast screenplay acting everything is just top notch I can't even tell you I don't have enough words to explain my feelings but really it's a must watch series of 2021 for every kdrama fan obvious when there is fantacy type with park bo young it'll be always great but also the male lead in seo in guk rose the bar of his acting though this crack breaking series,, still one of best kdrama I've ever watched.... hoping to fell the same until the end of this drama...
