The cold and picky Song Cheng decided to return to China for the sake of his ex, and taught at H University. He met Zhang Youzhi, who was sincere, cute-looking, and gentle. However, he accidentally learned that Zhang Youzhi's father was the murderer who caused his mother's death that year. In order to get revenge, Zhang Youzhi deliberately approached Zhang Youzhi. Zhang Youzhi had always liked Song Cheng's predecessor Xu Bai, but Luohua deliberately acted mercilessly. Zhang Youzhi was gradually moved by Song Cheng's disguised gentleness while getting along with Song Cheng, and the two slowly became together. Zhang Youzhi was injured in an accident, but he learned about his life experience in the hospital, and knew the truth about Song Cheng's approach to him. The sad Zhang Youzhi left the city, thinking that after the truth was revealed, the two would never meet again. It was only after Zhang Youzhi left that Song Cheng found out that he really liked the other person. It was unclear whether it was fate or evil fate.
