Chang Weijie (played by Ni Dahong) an empty-nest elderly man and Li Huiru (played by Kara Wai) a widowed elderly woman who collects scraps, are bound by a misunderstanding. Having a mutual affection for each other, they are, however, hesitant to make the next move. A clumsy statement of "I love you" ties the hearts of the two old people who are approaching the end of their lives, defying worldly prejudices and roaming in a sweet and romantic love. On the other hand, Xie Dingshan (played by Leung Ka Fai Tony) and Zhao Huanxin (played by Cecilia Yip Tung) are a loving couple who support each other throughout their lives. When the wife suffers from Alzheimer's disease, the husband takes on the burden of caring for her alone. His heartfelt words, "I love you", marks the commitment to be together until the very end of their lives. Through two stories of intense twilight love, the film portrays the different undertones of love, and also the best form of love – to love until life ends, yet love will never end. This story is based on the comic “I LOVE YOU” by Kang Full.
