Y/N, a 22-year-old former personal assistant, accepts a job working for a powerful CEO whose life looks perfect from the outside but is quietly falling apart. As she steps into his world, she becomes essential not only to his demanding company but also to his neglected home, where two young daughters are growing up without their mother’s presence and their father’s emotional support. What begins as a simple career opportunity slowly turns into something more complicated as Y/N becomes the one holding the household together. In a family built on silence, absence, and control, her presence brings stability—but also tension, dependency, and blurred boundaries that threaten to change everything.
