Reborn, I Married My Fiancé's Worst Enemy

In her past life, she was deceived by a scoundrel and set up by her cousin. Her family was destroyed, and a blade pierced her heart. Burdened with a terrible blood feud, she opens her eyes again to find herself a neglected concubine-born daughter in the Minister’s residence. Her birth mother beats and berates her at the slightest excuse. Her stepmother hides a poisonous heart behind a benevolent smile. Her legitimate elder sister smiles as she plots, intent on taking her life! Every member of this family has their own agenda, and none of them are worth a damn! Reborn, she will make her enemies repay every ounce of suffering she endured, a hundredfold! But... why has the scoundrel who was her enemy, whom she saved along the way while seeking revenge, come running to her side? “An enemy’s enemy is an ally. From now on, you dig the pit and I’ll fill it in. You get revenge, and I’ll invest.”
