Yan Ruoruo, the legitimate daughter of Marquis Yongning, has a pure heart and has been ignored and disliked by everyone in the house since she was a child. Late at night, she came across a man who was seriously injured and unconscious. She kindly hid him in the utility room and named him Dahei. Little did he know that the other party was Lu Qian, the Emperor of Beiming. Lu Qian was moved by her pure kindness and fell in love with her. The Hou Mansion wanted to give Yan Ruo to his cousin, so Lu Qian overcame all opinions and issued an imperial edict to establish the queen. Faced with the Hou Mansion's partiality for her biological mother, the evil-minded concubine, and the obstruction of the court, Lu Qian always protected her. Yan Ruoruo lost her cowardice and calmly took charge of the post. The two worked together to resolve the turmoil on all sides, healed each other, and stayed together for a lifetime.
