Been pondering this story for a while, as there clearly aren't enough of the mental asylum clichès around. 

It's primarily about Super Junior, but a couple of other bands will be featured, though not focused upon. Among others, SS501, Big Bang, SNSD and SHINee will make a brief appearance later. 

About the pairings; mostly KangTeuk with bits of EunHae, but there will be a lot of friendship between all the characters, and maybe some other pairings as well. 

Also, I'm really not familiar with mental disorders, or how psychiatric institutions are in Korea. I don't have the time and energy to spend a lot of time doing research for this story, so bear with the fact that this is fiction, and I take a few liberties to make the story flow better. If anyone has information to provide, I will gladly accept. :)
