After Becoming the Female Lead's Younger Sister, I Took Down the Scum [Quick Transmigration]

[I accidentally started this story in the wrong direction. The profession in the first world is a little sensitive, so I probably won't continue writing it. I might use a different upcoming story to write the later worlds.] [In some novels, the male leads are immensely powerful and ruthless, straddling the line between light and darkness. They'll do absolutely anything to possess the heroine.] Award-winning actress Xue Ning transmigrated. And not just once. 1. A top-notch actress and undercover policewoman younger sister vs. a gloomy crime boss with a possessiveness maxed out The male lead of Ultimate Surrender, Bo Ran, has an extremely possessive nature. After becoming attracted to the heroine's looks, he resorts to any means necessary to imprison her at his side. Xue Ning transmigrates as the heroine's twin sister, taking her place to get close to the male lead and gather evidence of his crimes. 2. A wealthy younger sister out to avenge her older sister vs. an emotionally detached, cold-hearted CEO 3. A lower-class younger sister with astonishing talent vs. a space tyrant bent on expanding his territory 4. To be decided * Maximum sweetness... a super satisfying story! All settings are futuristic or imaginary worlds, unrelated to reality. * A revenge story, so the male characters are all awful at first. Each world has a redemption arc in store.
