The son of a Han traitor who had let the Xianbei Mongols invade the borders, Jiang Shicai swears to restore his family’s honor, hoping to better the Hans’ lives through peaceful means. He believes violence is never the answer, but to gain respect, he finds himself fighting for the Xianbei. Ten years later, an annoying but handsome playboy, Dugu Xuechi, arrives as the incompetent new military inspector of Shicai’s region. Shameless, irresponsible, and obnoxious, Xuechi tests Shicai's patience almost every second. Despite their mutual dislike, Shicai finds himself drawn to the capricious man, especially when he sees the resemblance between Xuechi and his deceased best friend. Yet Xuechi's self-destructive behavior and refusal to accept help require attention that distracts Shicai from his goal for peace—and it doesn't help that Xuechi is Shicai's strongest political opposition. Haunted by a childhood promise he never had the chance to fulfill, Shicai must choose between his feelings and his values.
