The relentless disturbances that drive Woo-seong to madness are not accidental. They are orchestrated by his upstairs neighbor, Jin-ho, a journalist who installs a hidden phone to play continuous construction noises and bribes the downstairs couple to escalate the conflict.

Jin-ho’s plan is to isolate Woo-seong and frame him as a victim of poor living conditions. He intends to turn the breakdown into a sensational exposé, presenting himself as a whistle-blower exposing Seoul’s housing corruption.

While the residents’ representative, Mrs. Jeon, is aware of the chaos, she is not the source of the noise.
