Su Wanqing, the legitimate daughter of the Prime Minister's Palace, mistakenly trusted someone else in her previous life, and was plotted by Empress Liu and her family concubine, which led to the execution of everyone in the Su family. She also ended up miserably in the Han Palace. Before her death, she found out that only the powerful regent Xiao Jue had silently protected her. Once she was reborn, she returned to the age of sixteen and the eve of her haircut ceremony. With the regrets and memories of her previous life, she was determined to change her fate and pay for her debt with blood. She put down her body and clung to Xiao Jue desperately. She used intelligence and courage as a blade, and sincerity as a bridge. She worked step by step to smash the frame of her concubine, expose Queen Liu's conspiracy, and work with Xiao Jue to clear away the haze in the court. From deep palace hatred and family feud to knowing each other and standing side by side, Su Wanqing not only avenged the blood revenge of the previous life, protected the people around him, but also melted Xiao Jue's frozen heart. In the turbulent court, the two had a tacit understanding of rivals and a deep love of life and death. They finally got rid of the shackles of fate and worked together for a stable future where the wind and rain were gone and the warmth lasted forever.
