Fu Yuxiu thought that the saddest thing in the world was forgetfulness. When he met Qin Suoyi seven years later, who he thought he would never meet again, he realized that the saddest thing in the world was reluctance. Qin Suoyi used to believe that the fate between people will eventually come to an end. When she returned to the Netherlands, she felt that her fate with Fu Yuxiu had come to an end. After so many years, when they met again, when she looked at that familiar face, she thought, fate has no end, it just depends on whether you are willing to follow it. Once you meet some people, never leave them again. If you don't give up, hold on to each other and never leave.
