Guys, I have a question. Has it ever been mentioned why there's like the shade of black on his arms? At first, I thought it's the sleeves of his shirt, but then I still sees it when the shirt is off. So I though maybe he was stained with something black, but he looks like he washes himself, but it's still there. So, I wonder if there's an explanation to it that I might've missed.
