Yang Jiangyi, the versatile student council member, is calm and self-disciplined, and is a model student in the eyes of teachers; Jiang Xian, a sunny boy who loves skipping classes and playing ball, is free and uninhibited, and is a "frequent visitor" to the office.
Their first encounter took place in a stuffy office at the end of their second year of high school - Jiang Yizhen was leisurely blowing the air conditioner and playing with his mobile phone, while Jiang Xian, beside him, had his head drooped and was being scolded by the director.
At the beginning of their senior year of high school, fate cleverly arranged that the two of them became monitors of their brothers' class. Jiang Yi used her own focus and methods to rescue Jiang Xian from confusion and help him move towards college step by step; while Jiang Xian, with his sincere companionship and unreserved affirmation, quietly melted Jiang Yi's self-enclosed shell and relieved her deep anxiety and uneasiness.
Before the college entrance examination, they agreed with each other that they would go to Haishi University together and rush to the broader sky together. However, Jiang Yi's parents changed her college entrance examination application without her knowledge. The agreement was broken, the relationship came to an abrupt end, and the two became separated from each other and lost contact with each other.
Four years later, the sun is just right. They reunite unexpectedly. And at that moment, his sunshine finally once again completely lit up Jiang Yi's world.
