Unintentionally entangled in the promiscuous one-night stand lifestyle of his next-door neighbor, I-rok, a weary Dowon suffers nightly from the constant noise. Although he protested against the noise...which has grown even worse lately...I-rok merely brushes it off, leaving the situation unresolved.
Things reach a crisis point when Dowon even begins seeing I-rok in his dreams. Determined to step back and avoid getting swept up in I-rok’s complicated encounters any longer, Dowon resolves to keep his distance. However, his plan hits a snag when a drunk I-rok mistakes Dowon for one of his one-night stand partners.
