Ji Yuan, a liberal arts student, and Lin Xi, a science major, were classmates for three years in junior high school and the same school as high school for three years. At the same time, for some reason, they accidentally became roommates in the same dormitory. Ji Yuan was often ridiculed by Lin Xi because he failed to pass any of the three liberal arts and comprehensive subjects. However, Ji Yuan did not intend to give up resistance when facing Lin Xi who passed all the liberal arts and comprehensive subjects except physics. From then on, the two started a battle of arts and sciences that had been stumbling for three years in high school and even sparked "sparks".
