Introduction: Chu Yujuan, from a grassroots background, is an excellent senior high school girl. Her biggest dream is to attend the famous aristocratic university, Ailiston College. Yujuan's uncle borrowed money everywhere to send Yujuan to Ailiston. Murong Yunhai, Duanmu Lei, Shangguan Ruiqian, and Ye Shuo are the four noble offspring of Ailiston, each sunny and handsome, becoming idols adored by all the female students in the school. These four young men are not satisfied with the lives arranged by their parents and do not want to attend Ailiston. They desperately want the principal to expel them, so they conspired various pranks and became the headache-inducing H4 group for the principal. Inevitably, Yujuan and the H4 met. Due to her standing up for others, Yujuan became the target of H4's pranks. Through competition and rivalry, they began to admire each other and became friends. The H4 was also deeply moved by Yujuan's strength and independence, eventually becoming the four top students of the school.
