It is a character-driven comedy of manners about the discreet sexual lives of a group of interconnected people in an upper-middle class district of Seoul.

[1][2][3][4][5] Loose cannon Kwak Jang-bae (Shin Ha-kyun), a neighborhood policeman, is obsessed with his sexual prowess and continually wants to have sex with his live-in girlfriend, Ji-su (Uhm Ji-won), an English teacher at a private school who is bored with his macho behavior.

Forthright high-school student Ju Ja-hye (Baek Jin-hee) sells her sweat-stained panties on the internet and wants to lose her virginity to scruffy fish-sausage seller Choi-kang Sang-du (Ryoo Seung-bum); the older man is uninterested in her advances but Ja-hye cannot work out why.

Kim Gwang-rok (Oh Dal-su), Ja-hye's teacher, is a married man who is secretly into wearing women's clothes when his wife is not around.

Meanwhile, as his neighborhood has been marked for a moral clean-up campaign by the police, it's only time before Jang-bae also bumps heads with its denizens' licentious goings-on.
