SM Academy is well known to have famous idols from SMTOWN attending. Not only are they famous idols but they are all rich and good looking. The latest debuted group EXO is well known to be the kingkas in SM Academy. EXO is 12 handsome and good looking members but have a personality of a devil. TOgether with 12 minds together, they think of the evilest things possible. THe head master Lee Sooman dosent approve of their behaviour and wants their behaviour to change. One day while he was on the internet he spotted 4 international girls who come from across the world with different nationalities and richest girls in their country. He then thinks up a plan to enroll these 4 girls into SM Academy. 

Will these girs be able to change EXO's behaviours from devils to polite SM students?
