Due to some questions, here is the break down of everything on the Sehun Nightmare Teaser (click for full readability). Thank you to everyone who helped compile the information. (and for those who have helped with the image process. There are a bunch of you and you know who you are!)
ALSO, I will provide the back story for the concept of this nightmare: Sehun is an animal, he is in chains as can be seen on his left hand (the far one). Being imprisoned, he has gone insane and has scratched the walls with his claws in shapes and words with each a meaning their own, which are explained by the photos. The scratches on himself are there from his captor, and are not self-harm. Both ITSKPOPFASHION and SME do not accept or allow, nor do either approve of such behavior.
I died today in a car crash on the way, To tell you that I may, not make it through the night. And I apologize, for moving on so slow, I should of said these things, A long, long time ago. ‘Cause now it’s already too late, to go back and erase, The mistakes that I made.
