Lin Yu traveled to the world of "Love Siheyuan" and became a member of the Siheyuan. His father was a martyr, and his mother was an old worker in a steel rolling mill. Originally, Lin Yu and Qin Huairu had an engagement, but due to the sudden death of her mother, Qin Huairu finally married Jia Dongxu, an apprentice in the steel rolling mill, for her own benefit.
In order to maintain his image of not being vain, Qin Huairu worked with the Jia family to slander Lin Yu, causing his reputation in the courtyard to be seriously affected. Faced with such a dilemma, Lin Yu did not give up, but chose to face life with strength. He took over his mother's job and became a worker in a steel rolling mill.
