It tells the story of Xu Yanmo, a female assembly line worker who is forced to assume the identity of wealthy daughter Li Kesong to survive due to an accident. When she stepped into the luxurious world of glass, she discovered in Li Kesong's diary that this girl who was very different from herself had already glimpsed her life in an exquisite cage. As the wealthy family's conspiracy comes to light - from the old case of her mother's murder to the money laundering secret account, Xu Yanmo wears the shell of "Li Kesong" and circles around in lies, but unexpectedly pieces together a twin-flower-like fate fetter: Li Kesong paved the way for her with his life, and she lives as the light for both of them in the world of fireworks. When the Glazed Tower collapsed in the face of the truth, Xu Yanmo, with the courage of a sunflower, allowed the two souls to complete the cruelest and warmest redemption on their way to the sun.
