Don't Cry, Sis. Give Me Your Waist

A young lady who seems wicked but is actually kind and softhearted vs. a seemingly gentle little wolf who goes crazy with love [Clingy, Brooding Puppy + Younger Man + Corruption + Yandere + Redemption + Reborn for Revenge + 1v1] Ji Yunshang is a wicked supporting character in an adult novel. Her only mission is to drive the gloomy male lead completely to the dark side, or she'll die. So, when she sees him injured, she grabs handfuls of salt and sprinkles it into his wounds. “Salt disinfects. I'll only tell you this secret.” When she sees he's qualified to apply for a scholarship, she locks him at home so he misses the deadline. “I have so much money. I can buy you for the rest of your life, so you don't have to work so hard.” When someone at school confesses to him, she walks up and slaps them. “The first rule of being a dog is loyalty!” Gu Fengzhou's eyes turn red as he stares at her faintly reddened palm. He slowly kneels and reverently licks it. “Your hand hurts, and it hurts me too, Master.” Years later, Ji Yunshang is held captive by the man who has grown into an imperious, obsessive figure. His breath brushes against her ear, damp and warm. “Big Sister, remember, you were the one who provoked me first...” “Big Sister, I'll always be your most obedient little dog...” “Big Sister, I love you... until death do us part...” After dying and being reborn, Ji Yunshang awakens to the truth. Desperate to stay in this world and change her fate as a cannon-fodder villainess doomed to die, she devotes herself to completing the tasks assigned by the System. "Corrupt the male lead of this book, Gu Fengzhou. Reach 100% corruption within three months. Failure will result in complete erasure!" But Ji Yunshang doesn't know that the greatest hunters often appear as prey.
