Why did they dye his hair like that again?? Can anyone remind me plss

I think to mark him like he's untouchable. Singing did say that when mc becomes a part of them he'll be protected by jingi. I think that's why

To mark him as his property

it was so others in prison could see that the mc was one of the long haired dude’s ppl. it was so no one would lay their hands on the mc or mess with him

Thanks!!!!

Also, they fuck the dyed hair guy.
