Given Another Life, I Successfully Married into a Wealthy Family

In her previous life, Shen Siyu left for a distant land because of the huge gap between her and Mu Junhan's family backgrounds, as well as her own cowardice.

Can this pure and kind-hearted woman seize the opportunity to crush the wicked rival and become Mu Junhan's rightful wife, making herself a model of social mobility? (Both leads are devoted only to each other, in their past and present lives.)
