Dream, a student studying to retake the college entrance exam, meets Yi-soo, the owner of an online adult-good shopping mall and once a student at Hanguk University, on the rooftop. Yi-soo offers to tutor her math, and in exchange, Dream works part-time for Yi-soo's business as a customer service employee. After one incident, Yi-soo shuts down the online business and instead goes around the nation with a truck stocked up with adult products to sell. Dream and Soo-chan join him on this road trip, and the three's odd journey begins.
