That's a stupid curse. Why curse your beloved descendents to misery along w/ the one who wronged you? lol I would've just cursed the wolf and its descendents.
I wonder about that too. But maybe, just maybe the whole curse thing is not really the full story? Specially about the eat the heart of red cloak. It could mean something else or just literally eat the hearts. But, I still think it would be too simple if its really eating their hearts out.
Just read the first 3 chapters and unless the young master's attitude change, I'm already sad he's not going to be end game with female lead.
