Many years have passed from the tragedy, and still, Lee Hyukjae can't manage to forget. Why? Because it affected him in more ways than one. He literally refuses to show his face to anyone and wants nothing but to be left alone to drown in his own self-loathing. He isn't known as Lee Hyukjae anymore, but Eunhyuk. Eunhyuk is his second identity- His mask. Lee Hyukjae is now buried deeply into the back of his head. 

Eunhyuk doesn't want to go on any longer, he wishes to end it all. 

Donghae is an eighteen year old boy that suffers from mental retardation. He loves everything and everyone around him, he doesn't know of sadness or grief. All he could really do to deny the imperfect reality that he lived in was keep himself occupied in his innocent, happy thoughts that existed nowhere but his pure mind.

But what happens when child-like curiosity intrudes on a corrupted life?

What happens when innocence takes place in a life that knows nothing of purity?
