From Substitute Bride to His True Wife

On the wedding day, the video of the elder sister’s infidelity was exposed, forcing the younger sister to marry the Wall Street heir who was originally supposed to be her "brother-in-law". At first, the male lead thought the female lead was also part of the family’s scam, so he treated her coldly, on guard and with constant tests; the female lead, on the other hand, believed that the male lead married her only to humiliate her and take revenge on her family. Yet every external blow — media siege, the elder sister’s scheming, family pressure, commercial frame-up, pregnancy misunderstanding, the return of his ex, the side plot of a domestic violence victim, and the equity stake crisis — forced them to confront these challenges together. The two evolved from an "awkward married couple" to a "contractual alliance", from "mutual misunderstanding" to "standing side by side to break the deadlock", and finally confirmed their true love while protecting each other.
