Xue Wenxi comes from a poor family, and disguises as a guy to make ends meet by helping to transcript and copywrite books.

Coming to admire her talent, Feng Chengjun secretly sets a plan in motion that leaves her with no choice but to enroll in the Yun Shang Academy.

As the school only accepts male students, Xue Wenxi disguises herself as a boy (using her brother's name Wenbin), and lives everyday on thin ice to guard her secret.

Using her wit, kindness and charm, she also become close friends with the rebellious and unrestrained Yu Lexuan and the cold and aloof Lei Zexin.

As they inherit the legacy of their ancestors and strive to uphold their ideals, they also fall into a crisis as they become entangled with the conflicts passed down from the older generation.
