Chen Mu, a corner dessert shop owner, is soft-spoken and has a healing touch when making coffee latte art. Colleagues only regarded him as an ordinary young man with a bit of social anxiety and a habit of living alone. No one knows that he has a system that cannot be shut down after it goes online - the "Savior Remediation Plan". The system releases tasks every day, and the punishment is to deprive him of the peaceful daily life he cherishes most. But the content of the mission always makes him want to swallow needles: if he sees through a serial hunter disguised as a tortured person, he will receive a reward; but if he chooses to "cure" the other party, a hidden reward will be unlocked. Behind every "gentle treatment" lies Chen Mu's cold and bloodthirsty plan. He is a venomous snake that the city's underground forces are jealous of, but he wears an apron during the day and smiles harmlessly. Until a woman who claimed to be the "victim" appeared in front of the counter, and her smile was exactly the same as that of the murderer in Chen Mu's memory who burned all his files seven years ago. For the first time, the system released a choice mission: heal her, or destroy her. Chen Mu stirred the coffee gently, his smile did not change, but the snake pupils in his eyes slowly opened.
