Six years ago, due to the covert operation of Mrs. Lu, Xu Xi had no choice but to break up with the seriously ill Lu Yichen, only to discover that he was already pregnant. Xu Xi silently gave birth to their child, named Xu Lele, and passed away when Lele was 5 years old. Without his mother, Xu Lele took a photo of Lu Yichen and the love token from back then, and wandered alone for hundreds of kilometers with his little yellow dog who grew up together. Finally, he found his father, Lu Yichen. However, Lu Yichen did not believe that Lele was his child because he did not know the truth back then.
