Because of a bet to get the unapproachable Yan Yunzhi to accept her sachet, Sang Qi becomes the only female to enter an imperial college.
Sang Qi agrees to a bet that she can get Yan Yunzhi, the number one young master of Great Yan, to accept her sachet and watch lanterns with her on Spring Festival. Thinking that it would be an easy task, she hits a wall after being rejected repeatedly by him.
Upon learning that Yan Yunzhi teaches at the imperial college, she decides to study at the school. Her father, Grand Marshal Sang Gong, shamelessly cries and begs seven times for the emperor to allow his daughter to attend school. Just like that, Sang Qi gets in and becomes classmates with her childhood friend Zhou Wenyuan. At the same time, a mysterious organization disrupts the peace in the capital. Sang Qi and Yan Yunzhi join hands to find the mastermind.
