It was snowing in the early 20th year of Kangxi. The ten-year-old fourteenth elder brother Xuan Yi rescued the palace maid Su Bingxin who was scolded in Cining Palace. The veil she handed over Ziyan warmed his cold heart, and she became the closest person to him from then on.
Bing Xin is both a companion and a guardian. She uses allusions to persuade Xuan Yi to practice writing, resolves his frustration that he is not as good as his elder brother in riding and shooting, and accompanies him to face disputes in the study. When the biological mother took advantage of the visit to inquire about the prince's movements, she saw through the harem's plot but silently guarded him.
The two depended on each other in the whirlpool of imperial power, but Bing Xin knew very well that this forbidden love deep in the palace would eventually be shattered into moonlight on a cold night by the emperor's conspiracy and the conflict between his brothers.
