At her best friend's wedding, Song Miao slapped the bride three times in public because she was wearing a white wedding dress. Neither the groom nor the elders of the two parties stopped her, causing an uproar at the scene. Song Miao took the initiative to call the police and revealed that her true best friend Luo Xue was completely color blind and could not recognize white and would never choose a white wedding dress. The truth was revealed. Luo Xue was an adopted daughter. Luo Ting, the Luo family's separated biological daughter, had undergone plastic surgery to assume her identity. She also harmed Luo Xue and teamed up with her elders to conceal the truth. The groom Xie Tianyu knew about it but was forced to compromise and eventually committed suicide. Song Miao relied on evidence and agreement to expose the scam, and the murderer Luo Ting was punished according to law, and her injustice was avenged.
