Overview: Yoon-kyu is suffering from a terrible toothache but can't afford timely treatment due to a lack of money. One day, while staring into the mirror in pain in a bathroom, he hears the voice of a stranger. The man asks Yoon-kyu to buy him items like toilet paper and underwear. When Yoon-kyu, flustered, refuses, the man offers him money. Desperate for cash, Yoon-kyu reluctantly accepts the offer… and begins to grow closer to someone he should never have come face to face with.
