Han Tong discovered that he could see other people's "fate countdowns" - there was a number above each person's head, and when it returned to zero, it was the moment of death. But he soon discovered that this ability was far from simple as imagined. When he tries to save a girl who is about to be killed, instead of disappearing, her countdown is transferred to another person. Han Tong was forced to become the operator of "fate exchange". Every time he saved someone, another innocent person had to be sacrificed. What's even weirder is that someone has already understood his existence - a mysterious organization calling itself "The Fixer" came to the door, claiming that Han Tong was destroying the balance of the universe and must be eliminated. As for his most trusted partner, Shen Ye, the number above his head is always "0".
