What a captivating start!
Jeon Do Yeon surprised me with her fighting skills and her dual identity, a top-notch killer and a single mom. It's quite a contrast from her role in "Crash Course in Romance," where she played a kind aunt. Not that she's unkind here; I found her character to be very human, despite all the victims she's dealt with.

The plot was decent; I wasn't bored, but I didn't feel fully immersed either.
It felt like we were watching two separate stories—the one about the MK organization and Boksoon dealing with her teenage daughter.
However, the ending felt a bit lacking😐. There were many loose ends about MK that were left unresolved, and I doubt there will be a season 2, not that it's really necessary.

I enjoyed the fighting scenes, even if I've seen better.🪓🗡
Overall, I liked the whole cast, and there were many actors that I missed seeing. The production was solid, making it a fine movie to kill time with.
