“'Approach the only son who is set to inherit the crown.' That is your mission, River Winstead.” Suspended FBI agent River Winstead accepts an undercover infiltration mission in exchange for her reinstatement. Her mission is to become the lover of Alessandro, the son of her enemy and her first love who betrayed her, and steal information. "You aren't the only one who has changed, Alessandro. I’ve changed, too." River approached Alessandro disguised under the fake identity ‘Lily Gray' and succeeds in entering his home, a place he claimed none of his past lovers had ever set foot in.

 

However, as the mission continues, she finds herself helplessly drawn to this mysterious man and suffering because of it. Due to an unforeseen accident, her identity is exposed, and River barely manages to escape with her life. Regretting that single moment of hesitation, River vows to kill Alessandro at all costs. Yet the closer she gets to his shadow, the more shocking truths unravel… one by one. “I have something I must do. Just give me a little time. If you let me finish that... then I don't care if you end my life.” Alessandro — the only labels that should have followed were hatred and resentment. The word ‘love’ must never be attached to this emotion.
