A Japanese man, Hayase (played by Atsurou Watanabe), whose heart has been severely wounded by betrayal in friendship and love, is sent to work at a branch company in Shanghai by a Japanese car company. Depressed, he meets a pair of sisters in Shanghai. The older sister, Fang Min (played by Xu Jinglei), is beautiful, gracious, intelligent, and kind; the younger sister, Fang Lin (played by Dong Jie), is lively, cute, and youthful. Fang Min develops feelings for this melancholic gentleman, while Fang Lin also falls in love with this handsome man from another country, openly vying for Hayase’s affection and completely ignoring her childhood friend A De (played by Chen Bolin), who harbors deep feelings for her. Hayase, whose heart is like still water, gradually becomes moved by the understanding and gentle Fang Min, while rejecting Fang Lin. However, after Fang Min learns that she is terminally ill, she repeatedly refuses Hayase's love. But eventually, she is touched by this heartfelt man, and the two embrace tightly. Upon discovering her sister's relationship with Hayase, Fang Lin scolds Fang Min harshly, leaving her heartbroken. Fang Min's illness worsens, and after learning the truth, Fang Lin confesses to her sister. With the man who loves her by her side, Fang Min shows a quiet smile, lies in her lover's arms, and peacefully leaves this world.
