Don't Go to the Concubine's Ceremony

In her previous life, she was an unpopular legitimate daughter. Her stepmother bullied her, her stepsister framed her, and her good sisters used her to get into the background. She died with hatred in the harem, but she didn't know that there was always someone who cared about her. Once she was reborn, she worked hard to make those who abused her pay the price with blood. Stepmother, stepsister, and good sisters, she wants them all to taste the pain!
