The legitimate daughter of a noble family mistakenly trusted others in her past life, and was plotted against by her pillow-partner and concubine-born sister working together, causing the family to suffer catastrophe and die a grievance-filled tragic death. Once reborn, she returns to before the disaster arrives, putting away her innocence and weakness, laying out plans step by step, and exposing all conspiracy and deceit. The enemies who harmed her in the past lose all their momentum, coming to beg her for forgiveness. With a sea of blood and deep hatred before her, the female lead will no longer be soft-hearted, personally settling all grievances and grudges, protecting the family's stability, and living out a brand new life.
