Eight years ago, Shen Qingyan, a top-tier cleaner, was working at Mingsheng Group. She was fired for refusing to tolerate workplace sexual harassment. By accident, she had a sexual encounter with Su Mingxiu, the president of the group, who was drunk at the time. Later, she became pregnant and returned to her hometown, where she gave birth to her daughter, Shen Tangtang. After that, Su Mingxiu could never forget Shen Qingyan and had people search for her continuously for eight whole years. Coincidentally, members of the Su family went to the countryside to participate in a charity event, and unexpectedly recognized Shen Qingyan and her daughter.
