Shen Zhaoning was taken advantage of by the prince in his previous life and died late. Reborn at the age of fifteen, she disfigured herself and refused to be drafted, and took the initiative to marry Pei Yan, the sickly seventh prince - but she didn't know that he was the secret guard leader "Ye Xiao" who collected her body and guarded her tomb for seven years in her previous life. Pei Yan burned his soul to travel through time and space, and only had nine years left to live. The two went from trading to falling in love, and joined forces to fight against the prince and emperor who were also reborn. When the memory begins to disappear, when the truth emerges: his name is written on the jade pendant she carved before her death. In this life, it would be him who would forget everything, and it would be her who would protect him.
