Xiao Nanfeng, a hostage prince of Yan, was sent to Liang at the age of fourteen. Though he possessed formidable martial prowess, his status as a hostage forced him to endure humiliation and exercise restraint at every turn. During those years, he spent his days and nights alongside Shen Zhiyi, the legitimate daughter of the Duke Who Guards the State, and the two fell deeply in love. After overcoming countless hardships, he returned to his homeland and eventually became the Emperor of Yan. Later, the Shen family was framed by Zhao Song and his son. Shen Lie was unjustly imprisoned, while Shen Zhiyi was forced to marry Zhao Chong as a concubine. Upon learning the news, Xiao Nanfeng marched his army south without hesitation. Beneath the city walls, he faced Zhao Chong in a fight to the death. Ten years of suppressed endurance, a blood feud, and feelings left unspoken all came to a final reckoning amid the flames of war and political intrigue. A decade of waiting and missed chances culminates in a return, with the realm itself offered as the betrothal gift.
