Best friends.  Brothers.

A bond that can never be broken by anything.

Or can it?

Since they first met, Kim Kibum has always looked up to his best friend, Kim Jonghyun.  Even though Jonghyun was only a year older, he guided Kibum from elementary through high school and constantly went out of his way to protect the younger boy.  Kibum always wished he could be more like his confident and outgoing hyung.  He strongly believed that although his hyung acted childish and immaturely at times, Jonghyun could not be defeated by anything.

But sometimes, fate has a cruel sense of humor.

Did you ever know that you're my hero

And everything I would like to be

I can fly higher than an eagle

'Cause you are the wind beneath my wings
