An Sheng and Qiyue grew up together in a small city in the South. The two girls had contrasting personalities: An Sheng is bright and energetic, while Qiyue is quiet and reserved. They met one rainy day, when Qiyue handed an umbrella to An Sheng and disappeared. From that day on, they were best friends and attended the same school. Yet, they would eventually become tangled in a love triangle.
An Sheng helped Qiyue pursue Jia Ming, but Jia Ming gradually became attracted to the interesting An Sheng. In order to save their friendship, An Sheng decided to start a new relationship with another man. After graduating university, Qiyue planned her wedding with Jia Ming, but Jia Ming couldn't forget An Sheng. He left Qiyue in search of An Sheng, and that day, the friendship between An Sheng and Qiyue was ruined.
