Yelena Ivanovna Vasileva, a 21-year-old babysitter, is hired to care for two children living in an isolated, palace-like estate filled with wealth and silence. The father is never seen, never spoken about, and exists only as an absence that shapes the entire household. When Yelena is late putting the children to sleep, she finally comes face to face with Y/N—the man behind the locked doors. He is older, composed, and striking in a way that feels almost unreal, with a cold, Slavic beauty that makes him seem more like a myth than a man. What begins as a professional mistake quickly turns into something far more complicated as Yelena becomes aware of an unexpected and unsettling attraction. In a house built on control and secrecy, every interaction with Y/N carries unspoken tension—and Yelena is forced to navigate a growing pull she does not fully understand.
