Shen Wantang slipped into a book and became the cannon fodder female supporting character who conquered the yandere prince Xiao Yi. According to the original plot, she would be tortured to death by him. After awakening, she skipped Xiao Yi and went to the Regent's Palace to negotiate a deal with his biological father, Xiao Yan, who was in charge of the government.

And the yandere ex who was abandoned by her finally came to her door with red eyes. She shook Xiao Yan's marriage certificate in her hand and smiled: "My good nephew, call me aunt."
