The northern border of the Chouyun Empire is finally secure after years of fighting the neighboring Huangye tribe. Second Prince Huainan is relieved to leave the battlefield and finally go home to the capital... except there are more obstacles than he originally thought. Yingsu lives in a village near the foot of the northern mountains of the Chouyun Empire. When she finds a mysterious soldier with an obvious noble background lying injured in the snow, she does what anyone would do: she helps him. Little does Yingsu know that this man is none other than the Second Prince. Yingsu and Huainan's paths intersect as they struggle in a royal mess of conspiracies, drama, and danger. Will they be able to find their true selves in winter's bitter cold? Can love possibly melt the ice over the Prince's heart?
