Ri Dong received a message that Zhe Nan's company would take on the New Territories North project, but Ya Yan said she was confident that Gao Changsheng would get this project. Ya Yan met with Ya Si and proposed the hypothesis that the reason for Xun Xun's death could be due to Zhe Nan's delay. It turns out that Ya Yan hopes to prevent Zhe Nan from controlling the project by sowing discord between Ya Si and Zhe Nan.
Shen Zhicheng appeared at Gao Changsheng's home with a large belly, as it turned out he really had Gao Changsheng's child. Ri Dong, knowing that Ya Yan was sowing discord between Ya Si and Zhe Nan, wanted to stop her behavior. To prevent Ri Dong, Ya Yan asked Gao Changsheng to transfer Ri Dong, saying it would interfere with the plan to seize the New Territories North project.
Gao Changsheng vented his frustration by playing ball and heard the owner of the boxing gym talk about past regrets, which made him reflect on his own situation.
