The female killer follows the killer code of "I kill whoever pays me", but one day she receives a murder assignment from a repeat customer. The other party is a kind-hearted female doctor who lives in seclusion and never leaves the house. After observing the target for a few days, she discovers that she is actually the customer who placed the order. The customer hired someone to kill her? The identity of the cold-blooded killer and the "self-employed death seeker" employer are misplaced, and the emotional changes from "wanting to kill her" to "wanting to protect her" to "together for the future"
Concept: The cold-blooded tenderness of a charlatan killer
