To exact his vengeance against Jae-hee, Ma-ru approaches Seo Eun-gi, the cold and ruthless heiress to the chairman's empire and Jae-hee's stepdaughter. However, his plans become complicated when an accident causes Eun-gi to lose her memories and personality, leading to an unexpected bond. As secrets unravel and the past catches up, Ma-ru must navigate a dangerous web of ambition, sacrifice, and genuine redemption.
