Eun Soo, a struggling writer grappling with her lack of direction, becomes increasingly fixated on the mysterious sounds echoing from the apartment above hers. As she investigates the source of the disruptive thuds between rooms 401 and 501, her curiosity leads her to Ho Kyung, the enigmatic tenant above. Their lives intertwine as he, too, begins to notice her presence. Soon, Eun Soo unravels a startling reality about the noise—what she thought was mere imagination may hold a deeper significance, blurring the lines between her fiction and the truth.
