After Switching Grooms with My Sister, the Poor Little Thing Gains Fame and Fortune

Only before her wedding did Mu Sangyu learn that the boyfriend she'd dated for two years, the man she was about to marry, was her older sister's first love. The two of them were conspiring with her biological parents to elope, while arranging to marry her off to her sister's fiance instead. Faced with her parents' favoritism and her fiance's lies, Mu Sangyu smiled. Whoever wants the Mu family's prison can have it. Mu Sangyu wasted no time escaping that living hell and arriving at the Cheng family home. She thought it would be another pit of misery from the start. Who could have guessed that the pit would turn into a haven? Her kind, supportive in-laws and doting husband had her back. Nourished by love, Mu Sangyu grew into a fuller, better version of herself.
