The declining scholarly daughter He Qingci was sent to the Rong Mansion as a body double because her appearance resembled Shen Weixi, the "daughter of destiny" recognized by the Rong family of a century-old family. She was forced to imitate Shen Weixi's words and deeds, from the style of her bun to the style of her music, to replicate the traces of the late Bai Yueguang, and became a tool for Rong Xun, the leader of the Rong Mansion, to express his thoughts and fulfill his "destiny".
Rong Xun is cold and restrained. At first, he only regarded He Qing's poems as a symbol of completing the family's mission. However, as he spent time with her day and night, he was attracted by her resilience and unique talent hidden under the docile appearance. Her unique annotations when reading poems and the cool style of music that she inadvertently revealed when playing the piano gradually made his understanding of the "substitute" collapse.
When doubts about the cause of Shen Weixi's death gradually arise, the appearance of Yunyou painter Xie Zhiyao reveals the true nature of He Qing's poem. The breakup of Jiri Meilin allowed He Qingci to finally break free from the shackles of the "mirror image" and bluntly said, "I am He Qingci, not the dead soul of the Shen family." She tore the cracks in the old order of the Rong family with her escape, and it was only after Rong Xun lost her that he realized that what he was obsessed with was never destiny, but the living soul that he had ignored.
In the end, the two of them passed each other in the sea of people on the Shangyuan Festival. He Qingci gained spiritual freedom with his signed authentic poetry collection, while Rong Xun was trapped in family responsibilities and endless regret. This long song of the night sings about the heart-burning love that is shackles of identity, and also writes about finding one's own rebirth in the midst of destruction.
