I have the same feeling. I think his curse went berserk and somehow directly or indirectly caused the death of his parents. And the grandfather aka the Emperor, might have kept it a secret and put the blame on himself, that's what I thought too. Could be wrong but hopefully it's not really Ian that killed his parents. Usually manhwa like this dont go that dark haha
Ian killed his parents for sure! He went mad and caused the tragedy.
This ismt spoilers btw, this is just a hunch hahaha
