With cars, houses, and money all taken care of, she was about to enjoy a lovely retirement when someone stabbed her! She died, but not quite completely... An Affection Collection System made by the 2645 Universe bound itself to Song Qiyue, whose body had been declared dead, and sent her to an alternate world. Now more beautiful than ever, she watched the System's cash total keep climbing: +1, +1... +1,000,000... Maybe starting life over wasn't so bad after all. Song Qiyue rubbed her hands together, ready to stir up the world again, woo rich beauties, marry handsome rich men, and reach the pinnacle of life! The common-born girl at the elite academy, the haughty heiress, the seductive and ditzy supporting actress, the seemingly innocent little princess, the fragile underclassman, and the upperclasswoman determined to become an overbearing CEO herself... Who would turn out to be the reborn avenging goddess lying in wait? Cause trouble, cause trouble, all she wanted was trouble. The dashing playboy, the heir to a powerful family with a century of history, the cold-hearted young prince, the affectionate puppy, the sinister giant wolf... Which man would have the most adorable contrast? Sure, sure, all of them. In the end “What do you mean, I’m not an orphan?” Song Qiyue, now a billionaire, stood beneath the spotlights and rubbed her forehead as relatives suddenly appeared, claiming her as their daughter and little sister.
