Le Yao became a cannon fodder wife for the *sshole CEO, Nangong Jue. As she cherished her life, she quickly signed the divorce agreement and walked away. After she got far away from him, she let herself fly free. Strongly determined to succeed, she returned to school and became the most beautiful scholar on campus.
