this is prob the best villainess manhwa, she is opportunistic and learning, and not just knowing everything and perfectly solving everything unlike some of the other ones
also i feel like the hourglass subplot will have some serious effects later on so I would love to see how that turns out...
i'm guessing the reason she isn't reciprocating is because either she feels that it is her fault that hey killed his brother or that she feels that he has changed because of her...
