Zhao Qiaoyi (played by Wu Qian) and Yan Mo (played by Zhang Yujian) are deskmates in high school. One of them is carefree and confused, and the other is a famous cold-blooded academic bully in the school. It is such two people with very different personalities that ambiguous feelings gradually arise between them. When graduation was approaching, Yan Mo invited Zhao Qiaoyi to go abroad with him for further studies, but was rejected by the latter. After that, although the two were separated by thousands of mountains and rivers, their fate was not diluted. In college, Zhao Qiaoyi spent four ordinary years, and the only thing that increased day by day was her longing for Yan Mo. After graduation, Zhao Qiaoyi was cruel and decided to abandon everything and come to the city where Yan Mo was to start from scratch. The life of firewood, rice, oil and salt often caused conflicts between Zhao Qiaoyi and Yan Mo, and the obstruction of the outside world and the occurrence of accidents also made their love dangerous.
