It's hard to imagine a drama with a more difficult protagonist; she’s thoroughly unpleasant and unlikeable. I have to give credit to the performer for convincingly portraying such an objectionable person. The adaptation was fundamentally flawed from the start, guaranteeing its downfall. Like many extended webtoon adaptations, it struggled with excessive additions, dropped storylines, and a lack of clear organization as things moved forward. They didn't adjust well to the demands of bringing it to live action. Characters like Joo Da and her romantic partner were introduced to initiate the plot but ultimately felt insignificant, despite their initial importance to the story’s premise. The original idea held promise, however, what was delivered fell far short of telling a proper story, much less something enjoyable to watch.
