Go Through It Quickly, the Paranoid Yandere Villain's Favorite

Smart, calm, pretty, crazy/possessive and aggressive Jing Yan is bound to a useless system that is in danger of destruction, and he saves the little pity in the small world with it, and by the way... Changes the villain and falls in love with him. A certain villain pushed him into a corner and laughed evilly, wildly and wantonly: "You can kill me, but are you willing to do it?" A certain villain raised his chin and said with a smile: "Smelly scholar, how about you put down this book of saints and become a common man happily?" Even if you are on the opposite side, I will still run towards you firmly.
