Life, like clothes, sometimes gets wrinkled and shriveled. Jae Min, a 30-year-old job seeker who lives with anxiety that clings to him like grime, and Ji Seok, a 34-year-old voluntary unemployed person who threw away his well-ironed shirt and chose to stop. A healing romance between two men that blends in with the noise of the washing machines running late at night at a coin laundromat.
