In order to save his grandmother's old house, Xue Shengnan married Gu Peng, an abandoned son of the Gu family. They had been married in secret for three years. He was talkative, poor and only knew how to repair lamps. She thought each of them got what they needed. Until the divorce agreement was finalized - he was the one who adjusted the old revision documents that she stayed up all night to guard, and he repaired half of the old city that she wanted to preserve. The lamp repairer whom she despised was actually the real person in charge of the Gu family. Later, he trapped her under the eaves on a rainy night: "Mrs. Gu, divorce? I have been building the city for three years, but it has not yet entered your heart."
