Byung was a man that had no fortunate thing happen to him throughout his time on earth.
Right from being born with a disability that limited his body right to his parents dying shortly after and leaving him to fend for himself.
He could barely make ends meet and no one wanted to be friends with an invalid.
Byung's body got worse as time went on and a thought came to his head.
"What if I ended it all?" 
This thought eventually manifested into action as he threw himself in front of a truck, not just any truck but truck kun which made sure the job was done.
And without question, his life came to an end or so he thought.

Byung was reborn in a world as a goblin, a world with endless possibilities but most importantly, he didn't have the limitation of his disease holding him down.
However, he realized he was born into the worst race possible, a goblin.
This came with a massive disadvantage but the dual system he awakened showed him that he was brought into this race to lead them to greatness.
Byung had one mission, he was going to conquer this world with his dual system.
He was blessed with a rebate system, and an evolution system.

The first light of dawn crept through cracks in the cavern ceiling like thin fingers of blood, painting the unfamiliar stone in shades of red and gold. Kraghul's eyes snapped open, consciousness returning in a rush of pain and confusion. His body ached—wounds from the fights with Vrognut, Byung, and the other orcs throbbed like fresh brands. He tried to sit up, but his limbs wouldn't move. Thick ropes bound him wrist and ankle to a cold iron stake driven deep into the rock floor. Not ordinary ropes—these were woven with strands of steel, glinting coldly in the growing light, unyielding as chains forged in hellfire. He tugged hard, muscles bulging, veins popping on his green skin, but they didn't give an inch. Impossible to break, even for him.
