Huffing loudly as the hand shook at his shoulder if it weren't for the nine hundo in his pocket, he might have punched the prick, but there was too much of a chance for him to get this amount of money a second time.
So he would hold out... For now.
"I don' know about friends." He answered after a few seconds of silence, turning back towards Ren. "But we can be business partners. You got money, I need money. I got blood, you need blood."
