The K-pop chart-toppers are joined by up-and-coming rapper JooHeon.
It's only a few days into 2015, but it looks like the 2014 trend of K-pop stars teaming up with rappers is continuing on strong.
Throughout the track, Hyolyn cooingly asks a lover to teach her about loving, promising to be "a good girl" if he'll tell her if she's doing things right. The 29-year-old San E agrees to coach her, but adds in playful lines about smacking her feet if she does something wrong. Twenty-year-old JooHoen flies in for an impressive verse where she tells the diva, three years his senior, that he doesn't want to be seen as cute in her eyes and wants her regardless of the age difference.
