You don’t have to reread ur right. He knows, in one chapter myunga even says something like “it’s good you’re here you’ll heal faster the closer we are. It’d be better if we did it” something like that. He even fought the shaman guy when he found out. That’s why the guy is on a quest with the girl for a cure.

As of chapter chapter 61 (the current one as of the time of writing this), does "his grace" (I can't remember his name) know that Myungha is sick from trying to "heal" him from the curse? I got confused somewhere and kept expecting "his grace" to say something about how sick Myungha is at times, but he never says anything so I thought, "Maybe he knows why he's sick." But if he does, I've missed that part. Anyone got a second to explain that to me?
