this is one of the best kdramas for real, the urge to bing watch was high, it has been ages since i have done any review but i thought a show like this needs reviews, first the story is really interesting it kept me excited to check what will happen in the next eps, the only thing id say i was not interested in is the romance part, but it does make sense why its included ,because love is the reason why things took different path so it had to be included for certain things about the plot , id not say more to avoid spoilers
i also loved the ending and found it interesting, tbh i think this role really suit Park Shin Hye very well, it feels like the show is made for her and this is her best drama
