A Mistaken Marriage with Mr. CEO

Knowing she married the wrong guy, what would she do to deal with the subsequent marriage lives?
To pay for her brother's medical expenses, she had to replace her own sister to marry the wealthy family's elder son. She always thought she was married to the elder one, but she did not know her husband was nominally the younger son He Yi Ning.
He Yi Ning, the real heir of the wealthy family, the ruthless business emperor, the ruthless workplace tyrant, and her sister's dreaming husband. When she found out that the person who married her was He Yi Ning, she stunned and asked, "Shouldn't I be your sister-in-law?" He smiled charmingly: "Are you unhappy with your husband?"
