Xia Han and Chen Qianyuan met when they were teenagers and had a crush on each other, but neither one told the other. Many years later, the two met again, but they were no longer the same as when they were young. They each had their own jobs and lived a stable life. Xia Han and Chen Qianyuan actually still remember each other, but they can't express their love for each other. The past events are still vivid in their minds, but no one wants to go back to the cautious time in the past...
Concept: There may be many ways to like someone, but they all choose to love carefully. Maybe, many years later, they will meet again, but neither of them has the courage to say that they like someone. If the love is deep, just let it go.
