Amateur racing driver and magazine editor Deng Wenqian went to Lijiang to recover from her injuries. She met freelancer Lin Zhiyou, accountant Tang Yue, and director of Zhiyou Youth Hostel Li Tingting, which led to four different love affairs.
Wealthy girl Deng Wenqian fell in love with Jiang Yiheng, a street singer and "9th grade music poet", but was not recognized by her parents. After Jiang Yiheng ran away, he started a business in the name of controlling money. After many twists and turns, he gained both his love and career.
Lin Zhiyou fell in love with Yicheng during college. They broke up after a misunderstanding because Yicheng dropped out of school to start an Internet company. Later, he opened the Yue Youth Hostel with his classmate and close friend Tang Yue. Thanks to Deng Wenqian's skill, Lin Zhiyou and Yicheng are a perfect match.
Tang Yue fell in love with Lin Zhiyou's brother Wen Tianji during college. Wen Tianji, a top student, was not good at emotional intelligence. Later, through the joint education practice of Deng Wenqian and Tang Yue, he finally realized the love in his heart. Wen Zhong and Tang Yue took the lead in getting married.
After graduating from high school, Li Tingting joined the hotel. She was deeply loved by Lin Zhiyou and treated Lin Zhiyou as a relative. Li Tingting's love affair was rounded up by Jason, one of the passengers, an Englishman, which was quite interesting.
Because the author insists on the tragic and comic color, Deng Wenqian suffered from ALS six months after the collective wedding of four couples. Before Deng Wenqian died, Lin Zhiyou and Tang Yue gave birth to a pair of surrogate children, son: Jiang Wenyue, daughter: Jiang Qianzhi.
