A girl in Nuanxi who lost her memory for some unknown reason happened to meet the popular king Su Yang, and the two had to make an engagement due to a misunderstanding. In the future life, they will gradually develop feelings for each other by accident. . At this time, Nuan west's headaches became more and more severe, and the hidden memories seemed to be gradually unfolding in some opaque way. Su Yang's childhood sweetheart girlfriend Xuan Yi rejected Su Yang because she was infatuated with the eldest young master of the Shifeng Group, the Thirteenth Young Master, but after being rejected by the Thirteenth Young Master, she longed for Su Yang.
The Thirteenth Young Master, who returned from studying abroad, seems to have different feelings for Nuan Xi. Whenever Nuan Xi is in danger, he will always be the first to rush forward, but he never refuses to express his love to Nuan Xi. It turns out that he is not the real eldest son of the Shifeng Group but a guard of "Hell". But he desperately became the black knight of Nuanxi.
A series of scams designed by Xuan Yi to get rid of the imbalance in her heart caused a gap and misunderstanding between Su Yang and Nuan Xi. While Nuan Xi was surrounded by countless reporters, Su Yang was accompanying Xuan Yi in the hospital. Under a series of blows, Nuan Xi's memories came back like a flood. In the crowd, Nuan Xi was pushed into the middle of the road by someone unknown, and a truck came at a high speed. . . At that moment, Nuan west seemed to see himself a year ago, also lying in a pool of blood.
Time passes, and it turns out to be 5 years in the blink of an eye. 5 Years is neither long nor short. It can destroy a person, but it can also make a person successful. During Su Yang's world tour, a woman named Nuan Xi appeared again. . . .
When everything gradually came to the surface, Su Yang knew that he would never be able to hold Nuan west's hand again.
