Because their father Jian Zhishu was transferred to another job, Jian Fan and Jian Yao transferred to University Town A. Jian Yao has been over-protected by Jian Fan since she was a child, and has taken care of everything by herself. As a result, Jian Yao has a morbid and introverted personality, and is unaware and indifferent to worldly affairs. In order to get rid of Jian Yao's dependence on his brother, Jian Zhisuke allowed Jian Yao to enter the Hua SA Women's University, while Jian Fan studied at the Hua SA Affiliated Men's University. The two campuses are not far apart. This sister-in-law brother secretly resents his father for causing their brother and sister to be separated. He often sneaks into the Chinese Women's University under various pretexts and causes trouble in the name of protecting his sister. On Jian Yao's first day of school, Jian Fan got into trouble because of his sister and offended He Youqi, a privileged aristocrat in China. In order for her brother to avoid being ordered to drop out of school by the main school, Jian Yao begged He Youqi, a senior at the new school, to forgive him and promised to do anything for her. . .
