Yeon-Woo is the heir of Sipgangpa who takes on a dangerous disguise: posing as a boy to enter an all-boys school and assassinate the heir of rival Makgangpa. Her mission is clear, ruthless, and solitary. Inside the school, three handsome students orbit her disguise and unsettled feelings creep into her hardened noir life. One among them is the very Makgangpa heir she was sent to eliminate. Now Yeon-Woo must balance deadly duty and unexpected attraction. Each secret she keeps raises the stakes: discovery could mean war and death, but surrendering to love could betray everything she stands for. Torn between loyalty and longing, she faces a choice that will decide both her heart and her family's fate.
