Dowon, who has unwittingly become entangled in the promiscuous one-night-stand lifestyle of his neighbour Yi-nok, is exhausted and also tormented by the noise he hears every night. Although he has complained about the noise, which has become particularly bad of late, Yi-nok merely brushes it off, and the situation remains unresolved. Eventually, Dowon begins to feel a sense of unease after even dreaming about Yi-nok. Just as he resolves to keep his distance, no longer wishing to be entangled in Yi-nok’s complicated one-night stands, his plans are thrown into disarray when Yi-nok, whilst drunk, mistakes him for a one-night stand partner.
