Before he goes back to school, Sang-woo moves in with his aunt who gets divorced from his uncle who she's been having problems with for her carefree ways. One day, Sang-woo comes across an adult broadcasting application called Bong-al TV and sees his aunt under the name 'BJ Aunt'. She's covered her face with a mask but he's sure it's her. Sang-woo feels horny at the sight of her and wonders if he's a pervert.
