Synopsis: Xu Jingshu from class one in second year is a cold person who doesn’t talk much. If it wasn’t because the math teacher constantly sent her out as punishment, she may have been considered invisible in her class. Chu Youning, a new transfer student, falls in love with her candy-like smile. On certain afternoons, one can find him, the best student, personally teaching Xu Jingshu mathematics in the study room… sweetly.
