Kill Boksoon (2023) Ending Explained – Final Scene & Meaning

Bok-soon chooses to kill Min-kyu because her need for revenge and to protect her integrity overrides her concern about being seen by her daughter. She recognizes that Min-kyu will never stop hunting her and her family, so she eliminates the threat permanently. The revelation that Jae-yeong might witness the violence does not change her decision, she acts to end the cycle of betrayal and ensure her daughter's safety, even if that means her daughter sees her true nature.

Foreshadowing: Earlier in the film, Bok-soon's moral code repeatedly clashes with her employer's demands, establishing that she values personal integrity over self-preservation.

The ending deliberately leaves this ambiguous. The recording was streaming on a tablet, but it is unclear whether Jae-yeong was watching, awake, or asleep at that exact moment. When Bok-soon returns home, Jae-yeong is already sleeping peacefully, suggesting she may not have witnessed the violence. However, her request to keep the door open could hint at suspicion or a desire to protect herself.
