For Tang Nian'an, the greatest luck in life is to catch the person he likes when he was young. In the end, the two separated because of their youth. Years later, she has despaired of love and no longer has any illusions. But he kept standing where he was, as long as she could look back. He said: "When we are mature enough now, why can't you give me a chance to love and be together again." He said: "Don't talk to me about fate or not. I only know that fate needs to be fought for and persevered by oneself."
