Shen Qingwei, the daughter of the wealthy Shen family in the imperial capital, makes a bet with her childhood sweetheart Gu Beichen: Can she disguise herself as a slum girl and make the arrogant school girl Xu Moyan fall in love with the real her? In the past three years, she acted as a humble "dog licker", delivering breakfast, buying medicine, and being on call around the clock, but she only received public humiliation for the 1,081st time. On New Year's Eve, she dropped "Game Over" and walked away, returning to her status as a top socialite. After Xu Moyan learned the truth, he regretted it and joined forces with the darkened heroine Su Yurou in an attempt to take revenge on her and Gu Beichen's wedding of the century, but he didn't know that he had already fallen into her carefully crafted retaliatory web. This is a disguised game that started with a bet and ended with the true revenge of a wealthy family. When all the masks are lifted, who is the final winner?
