Replacement Bride's Real Love

Su Wantang was engaged to Fu Jinye, the richest man in the city, and she thought the feeling was mutual. Before the wedding she learned that the woman he wanted was her stepsister, Su Xinran, and that the Fu family was in the middle of an internal fight. Marrying Su Wantang put someone else between Su Xinran and the trouble, which was what the engagement had been for. Su Wantang went to Su Xinran and offered her the match. In exchange she took the one Su Xinran had been given, the blind young master of the Gu family, whom she had never met. She made Su Xinran promise to keep the swap quiet and went on playing her part in front of Fu Jinye until the wedding day, when the two brides changed places behind the veils. Su Wantang left with the Gu family. Fu Jinye finished the ceremony before he worked out which sister he had married, and the regret set in from there.
