The Little One Tears Up the Villain's Script

Novel blurb: When Jiang Xiaoman was three, she was bound to a System. The System told her that she was actually a lost rich heiress, destined to be cannon fodder, while the fake heiress adopted by her wealthy parents was the heroine. Jiang Xiaoman blinked and asked, "What's cannon fodder?" The System said, "You all live inside a book, and everyone has their own part to play. Basically, you need to cause trouble and turn evil nonstop. From now on, be a bad kid. See that little boy? He has an even bigger role than you. He's going to be a major villain someday. Go bully him now and give him a hard time." Jiang Xiaoman, still a little confused, picked a handful of colorful flowers and stuffed them into the boy's hands. "I'll give you a hard time!" The System: "..." That's not what I meant, sweetheart! Not that kind of hard time! The little boy said, "I don't need friends, and I don't need anyone to keep me company. I'm just a little cabbage nobody wants, destined to be abandoned." Jiang Xiaoman said, "That's not true. Everyone has a reason for being here. The System said you're really amazing, even more amazing than me. You'll grow up to be an incredibly useful person!" The System: "...??" Did I say that? Later, the System stopped giving Jiang Xiaoman tasks. She was terribly disappointed. "Big Brother System, why don't you play with me anymore?" The System said, "Try growing up and learning all your words first! You're going to be the death of me!!" Under the System's supervision, Jiang Xiaoman did her best to turn evil (not really), until her wealthy parents found her and brought her home. She patted her little head. "Big Brother System, what about my mission? Weren't we supposed to fight over the inheritance?" The System said, "Why bother fighting over the inheritance? You're richer than your wealthy parents now!" * The heroine is a real little kid * Adorable and heartwarming everyday life Theme: People are born good
