Substitute Queen: Palace Intrigue

The story takes place in the Song family of Yong'an Marquis Mansion. Song Mingyue, as the legitimate daughter of the mistress Madam Song, was promoted to the Imperial Concubine by virtue of her status advantage, but she faced the dilemma of being unable to have children. In order to continue her bloodline, Song Mingyue planned to let her twin sister Song Xingchen, who looks very similar to her, enter the palace as her substitute to receive the emperor's favor and give birth to a child.
