Modern elite assassin Morgan Calud dies and transmigrates into a woman with the same name. After Morgan's father died in battle, her mother disguised her as a boy from birth so they could maintain their position in the Calud family. As Morgan grows up, she yearns to reclaim her female identity but fears that discovery would mean death for both her and her mother. Planning to escape with her mother before her secret is exposed, Morgan is unexpectedly noticed by Shane Burke—the Aetheria Dynasty's only duke with a different surname, a man of overwhelming power and ruthless temperament. He brings her back to his estate, and from then on, she must outwit him daily just to survive.
