Ran Dongdong and Mudafu went to the psychiatric department to clarify Ran Dongdong's distrust of Mudafu. He discussed love with Mudafu at home and recalled his first love. All of this only existed in Ran Dongdong's mind and was not real. The double pressure of the case and family made Ran Dongdong suffer. Mudafu completed the project, and Ran Dongdong agreed to celebrate with him. The two came to their new house. Mudafu, who thought it was a two-person world, found that Ran Dongdong had made both families come over to let Mudafu move here to live.
