Zhou Jianchuan works away from home for a long time, and Zhou Hao is cared for by Zhou Huiqin. The school registers an incorrect phone number for Zhou Jianchuan, causing communication blocks and misunderstandings between Zhou Jianchuan and Zhou Hao. After returning home, Zhou Jianchuan learns about the situation from Teacher He, finding out that Zhou Hao's studies are stable and his lifestyle is frugal. After checking the bank statements, he rationally negotiates with Zhou Huiqin and Zhao Deli, confirming the repayment of funds and the cancellation of the IOU. Zhou Hao transfers schools to live together with Zhou Jianchuan, who accompanies Zhou Hao in adapting to the new school and gradually repairing their family affection.
