Zhang Zhijie will die on the wedding day in every life. In the fifteenth year of the Republic of China, she was reborn for the seventh time and found herself trapped in a cycle - every time she married into a different wealthy family, it would trigger a carefully designed murder. In this life, her fiancé was her childhood sweetheart, Gu Yanshen, the young master of the Gu family, and she finally saw clearly: it was not the groom who killed her, but the "most loyal servant" in every family. What's even more frightening is that Gu Yanshen seems to remember all the memories of his previous life. With seven days left before the wedding, Zhang Zhijie must find out the truth before the servant takes action - but she doesn't know that Gu Yanshen's rebirth started from his first life.
