Su Jin was imprisoned and killed by the powerful minister Pei Yan in her previous life because she was similar to his Bai Yueguang. Reborn on her wedding night, she chose to pretend to have lost her memory and put on the mask of a gentle and virtuous wife. During the day, she was a virtuous wife praised by everyone in the capital, advising him and taking care of the back house; at night, she secretly formed alliances with opponents, supported newcomers, and collected evidence. After three years of planning, once the net was closed, when she stabbed the dagger into his chest with her own hands, he smiled and held her hand: "Jin'er, I've been waiting for you to kill me. Because only in this way can you truly remember me." Su Jin then discovered that this revenge had been on his game from the beginning.
