“Whose child is it?” Winston and Yu-jin were once passionately in love, but due to a misunderstanding, they separated. Even now, Winston believes Yu-jin was involved in an affair with his father. After being cruelly abandoned, Yu-jin struggled to survive alone while raising his daughter, never expecting to cross paths with Winston again. Then one day, a fire forces Yu-jin out of his apartment, leaving him and his daughter homeless. At his lowest point, he learns that Winston’s father, Harold Campbell, left him an inheritance in his will. Desperate for any help, he decides to visit the Campbell estate. When they meet again, Winston still despises him, while Yu-jin only wishes to collect his inheritance and leave.
