The movie begins in a high school classroom where Chiho, Kyong, and Dong all like the same girl, Sue Min. Chiho tries to meet with Sue Min outside the classroom, but only manages to touch her chest. Dong gets into a fight with Chiho, but Kyong intervenes and suggests they act more maturely. Kyong proposes playing Rock Paper Scissors to see who can talk to Sue Min first. After a few rounds, Chiho wins and approaches Sue Min.
