Sun Mo has friends, but they all are not his true friends.
In his childhood, he always desired to have someone who will be always by his side no matter what the circumstances are, he desired to have a friend
A true friend
But he never got to have that one true friend, all he got were those who were after his wealth and status.
He had to pass his childhood, so he also didn't say anything against it.
But
Once Sun Mo met Chiyou, everything changed.
Sun Mo's main goal was to use Chiyou for his needs, his sole purpose was to use Chiyous strength to complete his evil dreams,
But as time passed by, he comes to realize the meaning of friendship which he had long forgotten.
Every time he would ask something from Chiyou, he would get it done without asking anything in return,
He gave a barren land called Sullegar just in the name so that he could have something on Chiyou, but the barren land that was given to him is now a land flourishing with greenery and fertility.
