From school to work and life, the male protagonist Qian Yu has always been full of love and contradictory thoughts; the female classmate Zhao Jia is lively, cheerful, delicate and simple, but lacks care. The two communicated in one afternoon. A cute girl Feng Qing appeared in Yu's college life. The two fell in love with each other, but Qing went to Shenzhen after graduation, and Yu stayed in the city. They were in the same office with Jia. Ban Zhouhua (seven or eight years older than Yu) met and had a relationship with her. At this time, Jia's fiancé found out that Jia and Yu were old lovers, and suspected Jia, and finally abandoned Jia, causing Jia to fall into pain. Yu took care of Jia again with self-blame, but could not get rid of Hua. When Yu was wandering at the crossroads of emotions, Qing came back, returning to the harbor and side of Yu for a love that was inseparable and for his wandering heart. At this time, the piano music - "Bird in the Dream" sounded.
