Lingwei, the concubine of the Duke of Zhenguo, and Juechen, the sixth prince, were both reborn with memories of their previous lives. In his previous life, Lingwei was treated as a pawn by his family and sent to the harem, and eventually became a victim of the heir apparent, and his entire family was destroyed. Jue Chen was framed and tragically killed by his brothers because he showed too much talent. After rebirth, Lingwei is determined to protect his family and break free from the shackles of fate, but unexpectedly discovers Jue Chen who has also been reborn. The two formed an alliance. Lingwei outsmarted his aunt and evil sisters in the palace to stabilize his position and secretly provided family information to Jue Chen. Jue Chen relied on his past life experience to organize the court, using the guise of "idleness" to confuse his opponents, but in fact he secretly cultivated power. In the process, Lingwei unites the oppressed women in the palace to form the "Red Sleeve Alliance", and Jue Chen uses his strength in the court. The two work together to smash the conspiracy of the concubine's relatives and reveal the truth of the tragedy in the past life. In the end, Lingwei becomes the matron of the family who can take charge of her own affairs, and Jue Chen ascends to the imperial power, and jointly protects the tranquility of the Jing Dynasty. !
