Quick Transmigration: Another Sweet Day with the Villainous Big Shot

(Quick transmigration + sweet romance + wild imagination + one-on-one romance with the male lead's fragments) A friendly reminder: 1. The settings vary from world to world, and the original male and female leads may be good or bad. It all depends on how the story unfolds. 2. The first world has a few potentially upsetting elements. Feel free to skip it if you don't like them, but please go easy on me. Be careful, or the author might follow your internet connection to your house and kidnap you! 3. The worlds build on one another, as does the character development. Please point out anything that could be improved. Li Wanwan gets hit by a car and dies on her way home from work. Talk about bad luck. When she wakes up, she's in a strange world and bound to a System that's still a tiny baby. Then she's told she has to win over a bunch of possessive, psychotic, corrupted, and utterly unhinged villains. Li Wanwan thinks it's so hard just to stay alive. The villains in each world are clearly powerful and impressive, but they've all had absolutely tragic pasts that made them want to destroy the world.
