After Kang Jian and Bai Yan broke up, their lives went through many twists and turns. Their love journey was long and they never knew the way back. The hands of fate were full of twists and turns. Where did their love end up? Are we forgetting each other in the world or are we letting each other know each other? Do you have a paper rose in your heart? A flower that never withers, a flower that stays new all year round in the long river of time, a flower that is green and beautiful in your purest years, a flower that grows old in your beauty, but you will still smile gently when you think about it. We all had beautiful first loves. We all treasure a shadow of our most beloved love in our hearts. Love is elusive, but marriage is very realistic. Love is a matter between two people, but marriage is a matter between two families.

What would you do if you couldn't marry the person you loved?
