When Zhou Yun's boyfriend Song Qingyuan proposed to her, warning bullet screens suddenly appeared, letting her know that he inherited ALS, borrowed the bride price, and intended to scam her into marriage. She secretly collected the medical records of three generations of the Song family's hereditary disease, and feigned raising the bride price to dissuade him in vain. Song Qingyuan and his mother came to their home to force her into marriage, secretly poisoned Zhou Yun's mother, colluded with a doctor to forge a leukemia diagnosis, and forcibly transferred one million in bride price to compel the marriage. Relying on the bullet screen prompts, Zhou Yun substantiated their poisoning and forged diagnosis. Song Qingyuan live-streamed to spread rumors and smear her, while Zhou Yun live-streamed the complete evidence to prove her innocence. Song Qingyuan was convicted for poisoning and defamation, and after getting out of prison his ALS worsened, with the family heavily in debt, the family of three ultimately meeting a tragic end. Zhou Yun and her mother started a peaceful new life.
