Plot
Gil Boksoon leads a double life. She is both the mother of a teenage daughter, whom she is raising on her own, and a legendary professional killer at top-tier killing agency MK Ent. One could even say that she is better at killing people than raising them. But one day, either out of motherly instinct or simply because there are limits to what even the ruthless Boksoon is willing to do, she refuses to complete an assignment. In doing so, she herself becomes a target.
