A vow made under plum blossoms in the snow was no match for a sudden imperial edict.
Ye Hui and Su Jun'an were childhood sweethearts, and they were privately engaged for life. However, on the day they were born, they were given the opportunity to marry the prince, and their beauty was locked away in the palace ever since.
The prince, a senior official, has been in love with Ye Hui for many years, and has been hired by the country, but he has never been able to enter the plum garden in her heart.
In the deep palace, there are turbulent undercurrents: pressure from the Queen Mother, calculations by concubines, criticism from the previous court...
When conspiracies and secret arrows strike, when innocence and true love are at odds, how should Ye Hui protect her love in the heart-wrenching palace?
And the young general who once promised her a long-lasting promise could only kneel down to His Highness and call her "Crown Princess".
