Dude...Chang knowingly pushed Ed into the debt he has now, so much so that he had to sell his body just to get by. Chang doesn't give a flying fuck, he wants to use Ed however he likes and is getting pissed off that after driving him into poverty with all that interest he built up, Ed has to sink as low as selling videos of himself spreading his ass for other men. Toxic. Chang is manipulative as hell, I'm sorry it's your opinion but I'll be fucking damned if I support this toxic relationship.
It appears my opinion is not acceptable to humankind..... hmmmmm....
I kinda like the ChangxEd happenin' right now. Chang kind of feels like the dark knight in shining armor to save Ed from his woeful existence. But hey let's read more chapters before judging huh? ╮(￣▽￣)╭
