10 years ago.
A 6 year old Kayin is drawing on his book in the living room. His hair black.and shorter.
A man opened the door and enters, carrying a suitcase with the label "EXO" on it. He walked passed Kayin as if he didn't notice him. It appears he's in a hurry.
A woman blocks his pass, her arms crossed under her chest.
"Why are you in such a hurry?" The woman asked.
"Honey, this is kind of important and I need to get to my room ASAP!" The man responded.
"And what's so important that you have to run off without even saying hello?"
"Classified."
"If you say so." The woman kissed the man before walking off to kitchen.
The man opened a door next to the kitchen and entered the room. The room had a round table at the center. A holographic display table. He placed down the case on his table and opened it too see that there was nothing other than a black cube and a metal disk above it. The disk displayed a green hologram of a person and started playing a message.
"It seems we have a traitor. I'm disappointed. I don't know why you wanted it but you stole it and so you will be punished. If you survive we'll know who you are. Rest in peace."
The hologram disappearing and what followed what an explosion. Both of Kayin's parents were incinerated the moment it exploded. Kayin was throw away violently by the power of the explosion.
Since he was the furthest away from the explosion, he survived. Their house was now on fire though and was crumbling. Young Kayin cried in pain as he tried to get up. Debris fell on top of him, pinning him.
He was in great amount of fain and didn't know what to do in this situation. He helt his arm out which was soon crushed by more debris and Kayin let out an ear piercing scream. All the bones in his arm were completely broken.
He turned his head to the side to look more at his surrounding, still unsure of what's happening and what to do. The fire continued to spread and he was now struggling to breathe from the smoke.
Something sharp fell amove and pierced his left eye and more things fell on his head, tearing some skin. Kayin was in an unbearable amount of pain at this point as more rubbing was falling on him, like it was trying to bury him alive. His vision started to blur, now given up on surviving.
Luckily help arrived in time. Firemen extinguished the fire and Kayin was brought to a hospital.
His eye had to be removed and his arm severed. He was then taken to an orphanage who would change his life for the better… and for the worse.
