**The fateful entanglement between the cold-faced lawyer and the freelance photographer**
As a top family lawyer in Jiangcheng, Lin Nuoyan accidentally met Xu Xingchen, a mysterious woman who was bidding for a guqin at an auction. This seemingly accidental encounter actually involves the secret behind the fire at the Lin Jia Qin Pavilion twenty years ago. When Lin Nuoyan took over the inheritance case of Xu Xingchen's mother, he discovered that the case was actually related to the disappearance of his father.
In the process of jointly investigating the inheritance case, the two fell into layers of fog: the missing piano score manuscript, the tampered fire report, and the sudden appearance of the illegitimate child claiming to be his father. As the truth gradually emerges, they not only have to face the test of family grudges, but also face their inner fear of love. When Xu Xingchen discovers that Lin Nuoyan is the little boy who saved her from the fire, how will the lovers cross the gap of time and fulfill their original promise in life?
