Hot service from sexy helpers! Oppa, I’m a college girl — do you want to try a refreshing body service?
Yeong-in is left in charge of her parents’ karaoke bar for a month while they are away on a trip. She runs it with her junior, Yoo-ra, but due to the recession, the bar has almost no customers, and the situation becomes so dire that she can’t even pay Yoo-ra’s part-time wages. One day, a male customer asks for a female helper, but Yeong-in’s karaoke bar doesn’t provide such a service. Just as the customer is about to leave, Yoo-ra boldly volunteers to act as a karaoke helper. The customer, pleased with the college girl’s service, pays generously. With this unexpected windfall, Yeong-in and Yoo-ra start actively offering helper services to customers, eventually going as far as having sex with them, and soon begin making big money. Other struggling karaoke bars quickly follow their example and see their sales rise. Word of the special helper service spreads among patrons, and the number of male customers rapidly increases. After a month, having earned a small fortune, Yeong-in suggests to Yoo-ra that the two of them open their own karaoke bar together.
