This show was touted as a Korean remake of Killing Eve and well, it isn't wrong. If you've watched Killing Eve, the similarities are there: female police officer/law enforcement agent goes on a cat and mouse chase with a female serial killer/assassin (in killing eve). This show takes on a more quirky/light hearted tone compared to Killing eve, which in my opinion doesn't work in its favor. "K" the female serial killer, is basically Villanelle but quirkier and less charismatic. Her "quirkiness" was played up too much it made it too over the top and unbelievable. This was actually the main reason I dropped the show. K's overacting was just grating on my nerves too much. The plot was also not sufficiently interesting to get me hooked on the show and make me able to look past the awful overacting. Koo and team already established that K was the killer around ep 4/5 so there wasn't anything left to compel me to continue. Also, the people who K was targeting were bad people, so it was kinda a good thing as well? I personally like a good revenge story so I didn't care to see K get apprehended. There was also some backstory about Koo's husband's suicide but it was meh.

Other plot points I couldn't stand was that I found it hard to believe that K had so much resources to carry out her various killings, especially the plan where she drugged Koo's 2 team mates and left them to die at sea. Villanelle had some outlandish schemes up her sleeve as well but she was an assassin part of an international organization. While K on the other hand seems decently well off with her aunt being some sort of insurance agent but definitely not chaebol level to have the means to pull off such stunts.

Acting wise: Lee Young Ae is decent as Koo but her performance did not wow me. K's actress on the other hand....ugh. Not sure if it was a production choice to have her overact and turn on her "quirkiness" meter to a million or maybe the actress' acting ability isn't up to standard to be able to portray the character convincingly.
