Chi-ho, Kyung-jae and Dong-woo are best friends who've just graduated from high school and turned 20. Chi-ho is an unemployed player living in the moment and whose number one priority is dating and chasing women. Kyung-jae is a goody-two-shoes university student whose goal is to get accepted at a corporate job; he's extremely shy around girls, but completely transforms when he gets drunk. And happy-go-lucky Dong-woo dreams of becoming a cartoonist, but when his family goes bankrupt, he's forced to become the breadwinner and take on several part-time jobs.
