This is a story about teacher-student love. Ye Diandian grew up with Ji Fan in three years from her initial admiration to her love for him, and then to her deep love. And Ji Fan will never forget the first time he met Ye Diandian. It was the re-examination before graduate school admission. Ji Fan, who had just come back from abroad to take a graduate student for the first time, saw the smiling Ye Diandian with bright eyes and pointed at him and said, "This is the one, he is the prettiest." At that time, Ji Fan's face was light and cloudy, but his heart was filled with spring water. Suddenly he remembered the poem, "The vermilion powder is not deep and even, and the idle flowers are light and springy."
