Shao Xue, Zheng Su Nian, and Zhang Qi are childhood friends who have grown up together. Their parents all work (or have worked) in the antique and museum trade, dedicating their lives to conserving priceless cultural artifacts. But as they get older, the friends’ lives start to take different turns, and their feeling toward one another start to change.
Zheng Su Nian’s mother, who has a great influence on both her son and Shao Xue, becomes dangerously ill. While for Zheng Su Nian, the loss of his mother will mean that he must take up her mantle, for Shao Xue, it inspires her to broaden her horizons, even if that means moving away from the neighborhood and friends she is so familiar with. She has secret feelings for Zheng Su Nian, who has also secretly been in love with her for some time. But Zhang Qi – whose true talent lies not with antiques but mathematics – also has feelings for Shao Xue. When he gets the chance to pursue his studies abroad, the trio comes to a crossroads in their young lives. Can love really be shunted to the sidelines so easily? Or will Cupid have something to say about the matter?
