A top antique restorer is silent, trapped on the day her boyfriend proposes. In the endless cycle, he discovered that he was the standard stand-in in the novel, and the ancient family paintings that he spent all his efforts to restore were actually the other person's token of memory for Bai Yueguang. Silence lets go of love and uses cycles to gain insight into everything. When the last cycle came, he stopped questioning and only calmly displayed the restored painting and irrefutable evidence at the much-anticipated proposal scene: "Mr. Gu, what you want to repair is never the painting, but your fictional past. And I am your last lesson." The cycle ended, and the silence moved the world, and the business tycoon was forever trapped in the yesterday called "lost".
