This is a love story about teachers and students falling in love on campus. It revolves around the story of Su Che, a 25-year-old painter and art teacher, and Xi Yue, a 19-year-old transfer student who gradually develops a subtle love relationship from the teacher-student relationship. Xiyue chose Su Che's painting class because of her weak foundation in changing majors, but was late for the first class of the semester. Although Su Che was rumored to have a cold temper, he was only gentle towards Xi Yue who was late, with an air of youthful and restrained ambiguity between the lines.
