Ou Xiduo, a junior high school girl with an innocent and cheerful appearance but a strong and passionate heart, has a dream of music and longs for fairy tale love. One day Ou Xiduo accidentally met Kang Shengyao, a sophomore boy from a technical school. The rebellious and cynical Kang Shengyao dropped out of school and left home to work because he was disappointed with his family, and embarked on the road of struggling for life alone. They originally belonged to two worlds and finally got closer to each other step by step under the guidance of love. In the Mood for Love, the age of passion, memories of youth. Thousands of sails have passed, leaving only residual regret. I just want to ask: "Merciful God, why do people have to say goodbye to their dearest people?"
