The real heiress green tea comeback

Diana, a sharp modern woman, awakens in a fantastical historical world, trapped in the body of the true heiress, unjustly cast aside for a manipulative imposter. Armed with a 'Green Tea System' - a cheat that weaponizes her cunning and social manipulation skills - Diana must reclaim her rightful place. Her mission: expose the fake heiress's duplicity, win back the affections of her estranged royal family, four powerful brothers, and the indifferent Crown Prince. Every task from the System, from subtle social maneuvers to outright confrontations, promises rewards that will rewrite her tragic fate in this novel's harsh reality. The stakes are her identity, her family, and potentially, the crown itself, all hanging precariously on her ability to out-play a master manipulator in a world where true power lies in mana and social standing.
