Eighteen-year-old Xia Di meets Zhang Yang, a girl she loves deeply. The two young people believe that love is everything, and thus start a wild and happy relationship. However, the two have completely different pursuits, different growth environments, and face family pressure, betrayal by friends, and various blows. In the end, can they fulfill the most beautiful vow they have ever made, holding hands and growing old together with their children?
We were so sweet, so beautiful, so trusting, so crazy, and so passionate. Why do we still have to run towards our own happiness and regrets and grow old?
If love can be sublimated, why do tears still flow uncontrollably after blessing?
If love can be let go, why is it that after saying goodbye, my heart is still uncontrollably sad?
Another thing, saying I love you in the end is the only thing I can do.
