Qin Ting was admitted to a general vocational high school in the county. Originally, Qin Ting thought that these three years would be spent as ordinary as the three years of junior high school, and then she would graduate successfully. But on the first day of school, Yao Yu, whom she hadn't seen for three years, also transferred to this school. Yao Yu was Qin Ting's classmate from elementary school, but due to her parents' work in junior high school, she transferred to a school in the next county. Unexpectedly, she transferred back to high school and was still in the same school as Qin Ting. The two hadn't seen each other for three years and had a deep relationship. They were inseparable almost every day, until Ouyang Xin's appearance broke the situation, and their relationship began to become complicated and subtle.
