The Female Villain's Self-Rescue Manual

PS double clean, no lightning, 1v1, safe lightning protection. She silently protects the male protagonist and grows into a tough female villain step by step. She transforms into the female villain of the entire book, and is a stumbling block in the relationship between the male and female protagonists in the original work. I want to change the plot, but it promotes the plot step by step. When you have done nothing wrong but are being hurt mercilessly, He was sincere but was abandoned like a shoe... He died unwillingly and gambled his life against the sky. After being reborn, she no longer wanted to accept the past, she wanted to change her destiny and be herself. So what about female villains? As long as they don't harm anyone, so what about villains? Can't the villain save himself? Can't a villain have his own love interest?
