After transmigrating into Love in the Courtyard, Lin Yu lives in a crowded courtyard as the son of a martyr. His mother, a longtime worker at the steel mill, had originally arranged for him to marry Qin Huairu. But after his mother sadly died of illness, Qin Huairu chose instead to marry Jia Dongxu, an apprentice at the mill. To protect her own reputation, Qin Huairu joined the Jia family in slandering Lin Yu, ruining his standing in the courtyard.
Faced with life’s upheavals, Lin Yu perseveres. He takes over his mother’s job at the steel mill and studies university-level courses in his spare time, eventually earning a college diploma. Through his own efforts, he becomes a technician and an assistant to the workshop director. Along the way, Lin Yu unexpectedly triggers and activates a sign-in System, which is sure to bring new opportunities and possibilities to his life.
