Xiao Feng is a lively girl starting her first year of university when her life is turned upside down by the arrival of her new upstairs neighbors: cousins Yi Cheng and Da Ye. Their arrival becomes much talked about at the university.
Xiao Feng starts to get along with Da Ye and falls in love with him. However, Da Ye doesn't have any feelings for Xiao Feng as he treats every girl the same way, although Xiao Feng sometimes feels that she is given preferential treatment. During this period, Yi Cheng starts to develop romantic feelings for Xiao Feng.
Xiao Feng confesses her feelings to Da Ye, who rejects her by saying that he doesn't know the true meaning of "love." Xiao Feng becomes heartbroken and depressed.
Yi Cheng pursues Xiao Feng, and they grow closer, which makes Da Ye uneasy. Just when Yi Cheng and Xiao Feng are about to become a couple, one of Yi Cheng's previous romantic interests demands his attention. They talk things through and move on from each other. However, Xiao Feng misinterprets the situation and becomes heartbroken again. Da Ye begins to develop feelings for Xiao Feng, and she starts dating him to help forget about Yi Cheng.
Yi Cheng continues to pursue Xiao Feng despite her being in a relationship with Da Ye. In class, Yi Cheng and Xiao Feng accidentally kiss; however, Xiao Feng tells Yi Cheng that she hated the kiss. Yi Cheng later confesses his feelings to Xiao Feng, while Da Ye becomes increasingly jealous.
Without telling Yi Cheng, Da Ye and Xiao Feng go on a two-day trip. Upon returning, Yi Cheng embraces Xiao Feng and tries to kiss her, but she pushes him away. Xiao Feng tells Da Ye about this, and Da Ye reacts by punching Yi Cheng.
The cousins learn that one of them must return to Shanghai to assist a new family business. Yi Cheng wants to ruin Da Ye and Xiao Feng's next date but hesitates as he does not want to hurt Xiao Feng. Da Ye breaks up with Xiao Feng, hating his jealousy as he falls further in love with her, and decides to go to Shanghai.
Yi Cheng asks Xiao Feng if she would rather he left. She tells him that he should decide his future on his own. Yi Cheng confesses his feelings to Xiao Feng one last time, and she rejects him, saying, "I can't carry such a heavy burden."
