About four virgin boys desperately trying to get rid of their virginity as it seems like everyone around them has done "it" already and are constantly confronted with people around them doing "it" as well. Harsh challenges and lost crushes are giving these guys a hard time but they are willing to keep their virginity until they find the one they want to lose it to in a pure way.
