He Tingnian unexpectedly enters the world of a novel and becomes the vicious male supporting character who will eventually be sent to prison by the female lead, Fang Suining. To save his own life, he starts changing the story from childhood, secretly bringing food and candy to the abused, starving Fang Suining and standing up for her, gradually pulling the prickly little wolf cub out of the mire. Years later, he deliberately keeps his distance from the female lead, never imagining that Fang Suining has already changed the course of her life to find him and is even hiding the secret of her rebirth. One desperately tries to escape while the other stubbornly pursues him. When a life-saving debt turns into obsessive love, the two who missed each other in both lifetimes finally manage to hold on to each other again.
