Gu Xuanming has been obsessed with Pei Jiaxue for twenty years. Even if he breaks the rules after drinking, he only gets perfunctory treatment from his "good friend". Until the nanny takes over and his illegitimate son Gu Nanhuai appears, Pei Jiaxue's preference completely shatters his illusions. Unable to bear the criticism, his mother jumped off a building and died. Gu Xuanming became the laughing stock of the whole city. He was even humiliated by Pei Jiaxue for favoring Gu Nanhuai, and finally fled in desperation. Three years later, he returned as the chairman of Shengfang Biotechnology, holding the power to settle old grudges. However, in the disputes in the past, he met Jiang Zheyue, who saved his life, and finally let go of his obsession and ran for his own happiness.
