The eldest daughter of the Bai family, who had been away from the capital for years, comes home with a delicate, handsome little husband! Bai Ran insists he isn't her husband. Yi Su smiles. “I'm the debt she owes.” The Bai parents sigh. “Child, picking someone up off the street should be a one-time thing. How did you do it again?” Bai Ran has picked up two people in her life. The first was her master, who led her onto the path of immortality. The second was a little doctor named Yi Su.
