I think he managed to get a hold of their birth records showing the they were related, and then proceeded to burn it. That way, there’s no way the brother can find out the truth. Hard to do anything anyway without the records for it.
And since MC got trapped under his thumb, he’s not going to seek out the brother anymore.
That’s how I interpreted it personally. Wonder if anyone else had a different interpretation.
I dont get it, what happened at the end? Did test show that he wasn’t his real brother?
