In the twenty-seventh year of Yong'an, Shen Yutian, the third young lady of the General's Mansion, witnessed Nangong Yiyou being buried in a sea of fire. Only then did she realize that she had mistakenly believed in the traitor Nangong Yichen, which not only killed the people who treated her sincerely, but also caused the injustice and destruction of her family. She died with hatred, but was unexpectedly reborn to the day when she was fifteen years old.
In this life, Shen Yutian carries the memories and regrets of his previous life and is determined to turn things around. She slapped the hypocritical Nangong Yichen in the face in public, protected the unicorn ornament that contained the secret message of collaborating with the enemy, and prevented the beginning of the family tragedy; she took the initiative to find the cowardly and inferior Nangong Yiyou who was hiding behind the rockery, and cherished the peach wood hairpin he gave, changing the disgust and alienation from her previous life.
Shen Yutian relied on his prophecy to help Nangong Yiyou strengthen the Dark Li Gang, collect evidence of the crimes of Prime Minister Xiaosong and Nangong Yichen, expose their conspiracy step by step, and clear the grievances of the Shen family. In the process of joining hands in revenge, the two gradually became more in love and supported each other. In the end, Nangong Yiyou eliminated the traitors and ascended the throne as emperor. Shen Yutian also got what he wanted. She joined hands with him to guard the prosperous world and usher in a peaceful and fulfilling life.
