Lu Jinghong, the daughter of a guilty minister, hid her red makeup and changed into a green shirt, and won the imperial examination in one fell swoop. She entered the court under the name "Lu Qingyan" just to find out the truth behind her father's false accusation of collaborating with the enemy and treason. She worked hard at every step, but she didn't expect that an imperial edict would tie her to the eldest princess Shen Zhiwei - the beautiful girl who once fed the koi in the imperial garden became her nominal wife.
In the tent warmed by red candles, she concealed the secret of her daughter's body and swirled in the whirlpool of the court and the harem. On one side is the secret arrow of political opponents who are pressing closer, and on the other is Shen Zhiwei's increasingly passionate sincerity. Lu Jinghong is struggling between lies and true feelings. He must protect the flame of revenge in his heart, but is also afraid of burning the tenderness in front of him.
When the mask of identity is pierced by stray arrows at the border, when an old case involves royal secrets, and when the enemy's iron hooves approach again, this "misplaced" couple will finally have to make a choice amidst intrigue, war, love and hate: Should they let everything go, or hold hands to break this chess game?
From winning the title in the Golden Palace to the bloodshed at the border, from red makeup hiding the front to holding the phoenix seal, their story hides the ups and downs of the Dayu Dynasty, as well as the two women's deep love and responsibility that transcend the world.
