To be honest, I don't like Hui. He's a hypocrite, saying that he is sincere towards Eve and whatnot yet would follow the first prince's orders without any protest. Sure he may had to do it so that he won't get killed in the throne succession war, but if that is the extent of his "sincerity" towards Eve, allowing her to suffer all this time without protecting her, then he's no better than all those people who only pay lip service. I pray that Eve, from start until the end, will never have any sort of romantic feelings towards him.
