In the tradition of raunchy coming-of-age romps such as Fast Times at Ridgemont High and American Pie, this Korean comedy explores the lust and life lessons of a group of young friends. Returning to college after a stint in the navy, Eun-shik (Chang Jung Lim) takes up a hard-core fitness regimen with the Cha Ryu group. But he’s distracted from his routine by gorgeous Eun-hyo (Ji-won Ha) and the female aerobics team that trains in the same gym.
