The general's legitimate daughter was deceived by her grandfather and was deposed. She was thrown into the cold palace, suffered all kinds of torture, and experienced a lifetime of humiliation. She regretted, she hated, and she swore that even if she turned into a devil, she would not let go of everyone who poisoned her, not even one of them!
After being reborn, she is like a demon from purgatory. She is willing to become a ruthless and scheming person. She fights against her cousins and uncles and aunts. There are people she desperately wants to kill and people she wants to protect with all her strength. For that person, she is willing to wash her hands and make soup while playing the harp and harp.
