How Could Anyone Stay Sane After Being a Villain for So Long?

[Beautiful, strong, and tragic madwoman protagonist + blackened, obsessive male lead + extreme push and pull + confinement and forced love] [Both leads are pure; happy ending] After her master died, Yin Xi was relentlessly hunted by the various immortal sects. Everyone called her a fiend who had betrayed her master and killed without mercy. But only Yin Xi knew that the demonic energy sealed inside her tormented her day after day, and she had no way to explain her suffering. Her master had schemed to ruin her utterly, then died without a stain on his reputation, leaving her with a pile of messes to clean up and a name cursed by everyone. She was tired. A heap of flesh slowly took human form. Yin Xi couldn't understand why she still wasn't dead, even after being reduced to this. She couldn't live even when she wanted to, and couldn't die even when she tried. Her will to survive was almost nonexistent. She only wanted to live quietly under an assumed name, but was suddenly and unexpectedly brought back to the capital. Facing the parents who had once driven her from home and siblings who were anything but friendly, Yin Xi tried to get herself killed every day. The moment someone touched her, she'd spit blood and pretend to faint. To her surprise, after she gave up trying, the world became much friendlier. Yin Xi drank, gambled, and visited brothels, while her usually image-conscious father put up with it and her usually timid mother stood up for her. Yin Xi caroused at the men's brothel, and her childhood friend and sworn enemy inexplicably showed up in a foul mood to wreck the place and keep her under control every day. When she finally finished making a scene and was about to leave the capital, the emperor offered her a marquisate and military command. Mingxin Academy wanted to hire her as an hereditary elder. The sect and senior brother who had been hunting her suddenly made peace with her... She was supposed to be the villain, so how had she become everyone's darling? Yin Xi continued to do whatever she pleased and court death every day. Until one day, her sworn enemy suddenly locked her to the bed and gave her a harsh lesson. Yin Xi was horrified. “How did you turn into an obsessive yandere?”
