In Songyu No. 1 Middle School, a key high school in the city, Lin Yang, a well-behaved girl who is a top student, and Gu Huai, a cool boy who is the school bully, are two parallel lines with no intersection. An unexpected seating arrangement forced the two to "bind" and start a campus life of falling in love and killing each other. Lin Yang couldn't stand Gu Huai's cynicism, and Gu Huai also scorned Lin Yang's "good student" behavior. The two went from being enemies to each other, and gradually developed a secret love as they got along day and night. However, family differences, misunderstandings from others, and academic pressure caused their relationship to go through twists and turns. In the face of many obstacles, can they stick to their original aspirations and reap a sweet ending that belongs to each other at the end of their youth?
