A noble daughter of an aristocratic family vs. A ruthless prince. Song Jinhe, who was born in a scholarly family, was the perfect candidate for the crown prince. But once someone plotted against her, she had no choice but to marry the second prince Shen Zhiyu, who was known to have a vicious reputation. When everyone thought that Song Jinhe must be in agony, they didn't know that Song Jinhe had always been interested in the second prince. The conspiracy you thought succeeded was just my trick. It is a mutual secret love, a two-way love, an evenly matched love, a story of the moon falling into its own night sky and illuminating each other.
