Codename: Ghost, My Powerful Family Is Just a Cover

When the real heiress, Gu Nian, is brought back to the Gu family, everyone sees her as a country girl who is "not fit for high society": timid and quiet, barely able to handle a knife and fork. She becomes the perfect backdrop for the fake heiress, Gu Siyu, and the main branch of the Gu family treats her as disposable.

Nobody knows that beneath her "clumsy" exterior lies a core member of the mysterious international organization Hive, known as Ghost. An expert in disguise and information warfare, she has returned to the wealthy family not to fight over the inheritance, but to uncover the truth behind her father's death in a car accident ten years ago. Her father was a member of a collateral branch of the Gu family, and his supposed accident was in fact closely tied to a conspiracy by the Gu family patriarch to sell state secrets.

Lu Zhiyan, an information broker, is the first to see through her disguise. He and Ghost are longtime rivals, sometimes enemies and sometimes allies. But as he gets close to Gu Nian, he's drawn in by the cool ruthlessness beneath her "timid" mask. He tests and provokes her, but with each clash he discovers that her ruthlessness is a form of self-protection, and her disguise is part of her quest for revenge. Their fathers, it turns out, died in the same conspiracy.

When Gu Nian's identity as Ghost is nearly exposed, when the fake heiress Gu Siyu discovers she's nothing but a pawn controlled by her family, and when the Gu family patriarch's ultimate conspiracy comes to light, three people with secrets of their own are forced to become allies.

She uses her identity as a "country girl" to lull her enemies into complacency, then wields Ghost's blade to tear away the wealthy family's veil of respectability. He uses information as bait, closing in step by step, yet can't help stepping in to take a blow for her. She goes from enemy to ally, striking back with the very identity of a pawn.

This battle, with the wealthy family as its chessboard
