Zhu Jiawei, the pride of the Chinese Dragon Group and the sharpest sword of the country, was involved in a long-planned frame-up. He bid farewell to his 20-year military career and accepted the order from his commander to enter Shanghai Donghai College to protect his beloved daughter. From then on, he became a school beauty, a teacher beauty, and a police beauty. No one knows whether it is a disaster or a blessing, and no one knows whether the love life will end perfectly.
