Fifteen-year-old {Su Weiwan} was pushed by her evil stepmother to fill the house of her paralyzed cousin. As soon as she entered the house, her cousin died in an "accident" and she became the orphan of Kefu's second marriage.
In a desperate situation, she was spotted by the incognito {Xiao Jinyuan}, and an edict was sent to the palace. The harem is treacherous, and the sickly noble concubine regards her as a thorn in her side and sets up traps everywhere; her stepmother colludes with her third cousin and wants to drag her into hell; even the prince who once showed kindness to her is jealous of His Majesty's preference and secretly plots against her.
But no one expected that this seemingly weak loli would actually use her tenacity to break up conspiracies and fight against villains, and even let the cold-faced Majesty {Jamie Xiao} make countless exceptions for her - rebuking everyone in the harem for her, killing the traitorous officials who framed her, and stamping out the rumors of "second marriage" for her.
The palace walls are deep, and {Su Weiwan} has more than one peach blossom for His Majesty, but she knows in her heart that the only man who protects her under his wings is her only support in this life. Let's see how the second-married loli can gain a foothold in the harem, win the emperor's exclusive favor, and trample all the villains under his feet!
