The Concubine Contract

As the most lethal assassin in the Seong Empire, Yeseo rarely encounters a mission that challenges her skills. However, when Emperor Ahon personally commissions her to uncover a spy lurking within his palace, she is forced into an unfamiliar role: posing as his newly acquired, seemingly vacant-minded concubine. To maintain her cover, she must project an image of devoted affection toward the emperor by day, while utilizing her sharp intellect to track down the hidden threat under the cover of night. What initially appears to be a straightforward assignment quickly spirals into a complex ordeal. The imperial court is rife with suspicious officials and intricate webs of political alliances, making it nearly impossible to identify the true traitor. As the investigation drags on, Yeseo finds herself struggling to balance her deadly profession with her absurd romantic facade. She must unmask the mysterious spy before the exhausting charade shatters her composure and compromises her carefully constructed disguise.
