You are from a very special family which hold magical powers. (kinda like a fairy) 

But what is the purpose of  your family together with the world governement? 

And why of al places must you begin your mission in the changing room of bigbang?! 

YOU :

Are 20 years old

Are very intelligent 

knows 10 languages 

pessimistic 

and you just don't give a damn 

But you are damned gorges

Went to school like a normal person and has friends like a normal person

now you bum around the house doing nothing 

Family :

is from a line a magical beings which the governemnt has control of. ( not in a bad way) 

They represent themselvs as fairys but their autonomy is very human like. (no visual wings) 

You and your family have 2 houses one on the ground and one in the air ( think of howls moving castle but the modern version of it)

Governement:

Was in the beginning scared of the fairy like beings ( 500 years ago)

But now they have come to a understanding that those fairy things can do no harm. 

So the pupose of the fairys is to diminisch stress in the world.... 

So that the world could be a better place or so you thought ...

What about your stress???? 

Mission:

YOu were given the mission to prevent the stress in south korea to escalate...

How ..........???

you did not have a clue because you were kicked out of house to do what fairy things with your life, and not to sit on your bum watching doramas and anime...

Side note your family does not expect a thing from you >>> ( but if you were serious you can be one badass fairy) 

YOU: there goes nothing ........ FML
