Lime and Eunjae (you), is the well-known Kingka because of their ulzzang looks. They want to be an artist for one of the boy band in Korea so they went to many companies to do the audition but got rejected until they reached the last spot, SM Entertainment where all the idol work there. Unfortunately, they were late because the audition for boy band had just finished.

Park Minyong (fic), known as SNSD's manager found them and asked them to join the famous girl group because he thought that the two notorious boys were a girl.

So, when boys in girls transform and must live under one roof, sharing one room with the member... How can they survive?
