is more like his brother did the same as his parents, keep him locked but at arms length, he felt trapped because they wanted to keep him in place but not even his family got close to him, so black haired dude did what he wanted, keep him locked and close
seems like a type of Stockholm syndrome. He grew up being trapped it's probably somewhat comforting because it's so familiar. The part he couldn't stand was being trapped while everyone who was around him kept him at a distance as well. So basically he's still trapped but he's not lonely. So really he needs some therapy lol
He said he felt locked up with his brother and ran off to lock himself up for his lover
