I'm Really Not a Witch

Reincarnating a few years ago would be fine, but I've inexplicably been transformed from a man into a legal lolita, and to save my life, I've had to become a villain! Xu Xianxian: "Have you ever seen a villain as pure and unpretentious as me?!" Troublemaking? Flat chested? 5 feet tall? It doesn't exist, it's all fake. There's no such thing. No matter how naughty you are, don't try to trick me into killing someone! This is the story of a side character who, stepping on everyone's path, becomes the ultimate villain to reverse the predetermined future.
