So, why do you really want to enter this kind of 'competition' since you are already famous in South Korea..even worldwide! You know what...I heard all of the tasks that given by the owner of this entertainment are not easy...are you really ready for this 'fierce' obstacles later.. *smirk*

There were a very strange envelopes in front of their apartments in the early morning and only a certain of KPOP idols will get that strange envelopes. 

They were given some tasks. First of all,they can get a fly to America and study about the arts of music there?! For 7 MONTHS?! And also had to take a leave for a while as an idol?! All of them of course didn't want to go at first but something just happened and changed their minds and all of 'them' have to go..

WHAT THE HECK IS ACTUALLY HAPPEN?! 

It is a very big chance for them to become a very popular yet famous singers and idols in this century if they 'accept' this challenges.  They will also get chances to meet the famous person like Kendall Jenner? and also can get a new job as well?

They also have to film their new reality show while they are 'studying' in America and all of their fans will get to know about their fun activities there as well. 

Or....

What if the feelings between the idols suddenly bloomed and have a feeling with each other?
