On their fifth wedding anniversary, Song Wanying discovered that her husband He Zhisong was having an affair with her nanny Fang Xiaoqi. She also learned that the two had transferred her property and planned to accuse her of domestic violence and seize power the next day. The next day, the two staged a scene of "jumping off a building", injuring their adopted daughter Song Beibei and instigating their "son" Song Shule to frame her. Song Wanying responded calmly, pretended to be under surveillance to collect evidence, and continued her plan after failing to expose the truth in public. Song Shule suddenly suffered from a blood disease and needed a transplant. Song Wanying's match was found to be unrelated, and Fang Xiaoqi admitted that she had an illegitimate child with He Zhisong. Fang Xiaoqi's ex-husband asked for money to get a match. When Song Wanying resolved the situation, she learned that Song Beibei was her biological daughter. Song Wanying consolidated the evidence and sent Fang Xiaoqi to jail, and He Zhisong's crime was also exposed and jailed.
