A car accident changed the fate of twin sisters. Osane Lius, who was supposed to study abroad, was forced by her mother to replace her elder sister and marry the powerful Haw family.

"Your sister's body is no longer able to carry children." "So...you can't escape until you give birth to a healthy child."
