Sora believes that her younger sister Eunjung needs to loosen up a little,  she's a complete workaholic,  has never been on a date.

The the girl's 23 for crying out loud and has never had her first kiss. 

But sora knows her sister secretly  craves adventures,  action and romance.

So being the brilliant sister she is,  she sets her sister up on a blind date. 

Not knowing that was the best and worst mistake a girl could make

Yongguk,  leader of the most feared gang called B. A. P in Korea, is tired of his right hand man's constant sleeping around. 

Yeah,  he himself has slept around,  but himachal is the worst ever. 

The dude sleeps  with a total of four different girls,  one after the other,  per night. 

Afraid that his best friend might contract some kind of STD, he with the help of his gang members. 

Tricks himchan  into attending a blind date,  knowing fully well that it might be the stupidest idea he's  come up with considering who they are. 

He'll  just have to change that worst into the best.
