During the Yongning period, the imperial power declined and the gentry took power. Princess Yuan Shutong of Daliang has a stunning appearance and outstanding talent and learning, but she has become a pawn in the family's game. Her cousin, Xie Linfeng, the legitimate son of the Xie family in Chenjun, had been in love with her for many years and was forced to marry her due to family power. However, Yuan Shutong only hated him and would rather entertain the actress than get close to her. This attracted the attention of Xiao Che, a son of an aristocratic family in the separatist faction, and Shen Yushu, a talented man from a poor family.
Xie Linfeng went to the battlefield to prove his identity, but Shen Yushu "sneaked in" while Yuan Shutong gradually fell in love and dealt with Xiao Che in order to dissolve the engagement. Xie Linfeng returned triumphantly, but even though he noticed her "change of heart", he still waited patiently and guarded her secretly. Yuan Shutong used Xiao Che to break off the engagement and married Shen Yushu, but Xiao Che forced her to stay.
Xie Linfeng could not let go of his obsession and "entered the palace" regardless of his status. Yuan Shutong also pretended to imply divorce because the royal family needed Xie's family. After the Dongchuang incident, Xie Linfeng drew his sword at the banquet to force the election, but he realized the fact that he was being used. In the end, Xie Linfeng was willing to become an outsider, Xiao Che compromised, and Yuan Shutong found a way to survive in the troubled world of love and power.
