The darkness of his childhood had overturned his life.
The parents he loved suddenly changed drastically overnight.
The betrayal of his mother turned the once gentle father suddenly brutal,
Those three days and nights were the darkest period of his life; he was brought back to the Nan Family.
From then on, almost everyone in the Nan Family said he was a bastard, his mother a slut, and his father a spineless loser...
It was later that he learned the rumors had been exacerbated by his seemingly kind second uncle at the Nan Family, who was actually behind it all.
The purpose was to enrage his father, to break him down.
And he saw human nature clearly all at once.
Human nature was so cruel, he realized.
Thus, he came to hate betrayal immensely.
His world also changed all at once.
He could no longer see any sunlight; in this world where the strong prey on the weak, there was no light or warmth for him.
