Shen Jingyi and Lu Yanting, a period of sadomasochism wrapped in fate begins. Shen Jingyi complied with her father's last wish and was forced to marry Lu Yanting on the grounds of master-disciple relationship. However, not long after the marriage, Lu Yanting took root in the closed institute and suddenly lost contact for four years. She was unexpectedly pregnant, but was maliciously speculated by the Lu family. She was accused of having an unknown origin of the child and was cruelly kicked out of the house. Since then, Shen Jingyi has lived alone in the old house with her son An An, enduring rumors, criticism and strange looks from her neighbors all year round. She has been running around day after day just to apply for a household registration for her child and support a stable life. Just when she was desperate, Lu Yanting ended her assignment and was transferred back to the local area. After an unexpected reunion in an alley, he witnessed the mother and son being humiliated. He recognized his biological son at a glance based on his bloodline, and shattered all rumors in public. After learning about his family's paranoia and arrogance, as well as Shen Jingyi's four years of suffering, Lu Yanting was filled with guilt and wanted to spend everything he had to make up for his mistakes. Shen Jingyi, who has been tempered by the world, has long been at peace. She just wants to go through the procedures for settling in An'an, draw a clear line with him, and divorce him decently. But Lu Yanting, who was burdened with promises and debts, refused to let go. The two people who were estranged in the past began a belated approach and redemption between misunderstandings and debts.
