Lin Xiaoman and Chen Chen were once the best classmates in elementary school. During their childhood, they made an innocent promise to "be together when they grow up." After graduating from elementary school, fate caused them to get lost in the vast sea of people. Ten years later, on the university campus, Lin Xiaoman, a "joke girl" from the Art Department, and Chen Chen, a "rational academic master" from the Finance Department, reunited unexpectedly. From the stupefied encounter in the library, to the tacit understanding under the cherry blossom tree, from the clumsy reacquaintance, to the long-lasting companionship, two seemingly completely different souls re-intertwined during their college years. There are no grudges between wealthy families, no dramatic conflicts, only the warmth and growth of ordinary people. This is a story about time, fate and choice - when the childhood promise sprouts again in the adult world, can they join hands to move towards the future they have promised?
