Oops! I Ended Up with My Sister's Man - Episode 12

Cedric returns to his parents' house with a bouquet and his new wife, Katie. Lilian, the mother, gives Katie the Notts family bracelet and offers a warm welcome, but the patriarch refuses to accept the marriage—reminding everyone he originally chose Eliza and insisting the family's reputation must be preserved. He grants Katie a three-month trial to be trained into a proper lady and warns he will never acknowledge her if she fails. Cedric insists they are legally married and vows to protect her. The episode closes with the three-month deadline hanging over Katie's place in the family.
