The rough and wild delinquent, Jang Tae-ho, gets dragged off to his grandma’s countryside house on the very first day of summer break, thanks to his parents’ brilliant plan (or maybe a scheme).
Waiting for him there is none other than the gangster heiress, Min Ju-a!

With a gun pointed straight at a stunned Tae-ho, Ju-a declares:
“I kidnapped you to make you my underling.”

And so begins the chaotic, action-packed summer break of the delinquent Jang Tae-ho and the gangster heiress Min Ju-a!
