Don't Try to Conquer the Yandere Male Partner

[System+book-traveling+beautiful, strong, yandere+redemption+lasting love] Su Lulu dressed up as the scheming White Lotus female character in a novel she read many years ago. System: [Host, you must prevent the original male partner from turning black before you can go home. Not only that, you can also get a huge sum of money. Isn't it a joke to ask her to stop a big demon from turning dark? But she endured it for the sake of returning home and the huge sum of money. She would stand in the way of the male partner when it was difficult, and fall in love with him when there was danger. She lived in fear next to the big devil every day. But Gu Yiting is a murderous and extremely perverted demon, and he can't be influenced at all. System: [Warning! The blackening value of the male partner is about to reach 100%! Su Lulu was ready to quit and plan to pack up and run away. But who would have thought that the aloof Demon Lord, who had countless beauties and was looking for someone, turned his hair white, and his blood flowed into a river overnight, and there were piles of corpses. This incident spread to people from all walks of life, and everyone was curious about who the woman was. When the two met again, Su Lulu had been imprisoned, and she begged him with tears in her eyes to let her go. Gu Yiting stared at her with a pair of red eyes and said crazily: "You will never escape in this life!" Ps: It's nonsensical. If you're very logical, don't read it. My writing skills are limited and I'm inexperienced.
