In 2003, 19-year-old Yi Chuxin came to Taiwan for exchange alone and met Lu Yuhan, a talented, sensitive and funny student. The two people's different growth environment and values make them repellent and attracted to each other. I work hard at first, but I don't know what my real dream is. All my efforts are just to get ahead. Yuhan enjoys the present but has no plans, and his spontaneity and indulgence for the future are lamentable. Out of their shared love for literature, the two became familiar with each other, and gradually found the missing piece of themselves in each other. The original intention encouraged Yu Han to embark on the path of music, and Yu Han's talent and charm soon gained him recognition. Just when their ideals and love were just beginning, their original intention was to return to the mainland. The two knew that they would never see each other again, and they agreed to forget each other with beautiful memories, but they should also use the spirit they learned from each other to become better selves.
Ten years later, Lu Yuhan has become a rising star, but his original intention is still struggling in the mud of life. At a certain concert, Chuxin was sitting in the infield area and burst into tears when she heard the song Lu Yuhan had written for her when she was in love. . . .
