Transmigration and rebirth + reopening an old case for her family + joining forces to uncover the truth + reforming the court
A sniper from a special forces unit dies in an accident while on a mission and transmigrates into the disgraced legitimate daughter of a marquis's household. She vows to reclaim everything that belonged to the original owner.
On her return to the capital, she meets the male lead, a proud and calculating man with formidable martial prowess and intelligence.
Though they should have been enemies, the two join forces to uncover the truth and reform the court. In the end, they expose the Empress Dowager's maternal relatives' plot to overthrow imperial rule, and the two powerful leads spend their lives together.
Along the way, they grow fond of each other and ultimately marry.
Female lead: “So I'm just a tool?”
Male lead: “At first, yes. But you were so charming, I couldn't resist.”
