It was mentioned that the upside-down ghost was probably attracted to Simone’s death energy, and so she followed her in the manor.
Did we read the same manhwaaa, the upside down woman was attracted to Simone's energy and the Dark Mage is not the one who cursed Jace, Jace was already cursed when the dark Mage offered a "solution" to the desperate grand duke and duchess. He teaches the grand duchess something sinister ritual to "cure" Jace. It's also revealed that the Dark Mage knows something more about the Manor that's why they are looking for him. There are still ongoing mysteries that aren't resolve entirely and probably gonna be related to future curses
But the item that cursed Jace is in the room the dark mage used, so it was kind of implied it was the dark mage all along who cursed Jace, that is what's not clear.
I know, but all those times the woman is with the man, she didn't exactly do anything, she only becomes more vengeful after she was apart from him.
And that doesn't really make much sense, so she just found the courage to torment him after she was away with him? Ghosts in this story could literally do more than be transparent. She could have tormented the man's residence when she was with him, it's not like she's restricted or anything.
I remember an info that said the merchant/noble came to the duchy to bury this woman. So, what are the odds of tormenting the man's residence when she haven't yet arrive there? And if by chance you are thinking he just went there to visit the woman he buried, that doesn't make sense either. Or if you're thinking he went there for business, I bet he has manpower to do that without showing up himself, after all, his business is mostly on other nations, not in this empire. I think she's yet to haunt this man because she's only became a ghost herself, and before doing so, she met Simone and was attracted to her energy. So instead of the guy's residence, she haunted the cursed mansion in search of the person she wanna get revenge on.
You coming up with your own theories just proved my point
It's good and entertaining, but there are really aspects that makes you scratch your head because it doesn't make sense, and some parts that is still not answered even at the end of each case. For example, the upside down woman, she's always been with the one she's looking for, then she goes to the mansion along with FL. The case of Jace, if the dark mage the one who cursed him then what was the motive?
