An ordinary genetic test tears open the cruelest truth of a seven-year marriage: none of the three children is his. The moment engineer Ying Qingfeng receives the test results, his life falls apart. The loving family he thought he had was nothing but an illusion built on lies. His wife Lan Weiwei's betrayal and the three children's different biological fathers plunge him into an abyss of truth and emotion.
From shock and anguish to a determined search for answers, Ying Qingfeng embarks on a difficult path to expose the betrayal and find justice. Covert investigations, courtroom showdowns, and media storms follow one after another. The psychological crises the children face when their identities are revealed leave him torn between hatred and love. When the court's judgment finally comes down, deciding who gets the property and the children, he realizes that blood ties can be faked, but the feelings he has invested over seven years cannot be severed so easily.
Caught between social ethics and personal dignity, Ying Qingfeng goes from victim to seeking redemption. He begins to wonder: Is fatherhood defined by genes, or forged through love and responsibility? Nonfather is not only a suspenseful investigation into betrayal and truth, but also a profound lament for humanity, law, and the bonds of a family unrelated by blood.
