It’s so messed up. SPOILERS:
Note: I read the spoilers on NU website but apparently, at the end, she never clears up the misunderstanding. The reason why she wants to go back to her og world is because of her mom. Meanwhile the husband and son think that she’s trying to leave because of another man and because they’re demons. She never clarifies why she wants to go back! In the end, she feels guilty so she gives up on going back to her world but the duke cuts her tendons so she can’t walk on her own. She’s stuck in a wheelchair for the rest of her life but the duke forbade everyone but himself to be able to touch the wheelchair. She’s also stuck in the duchess’s room as a result. She plays her part in their little family dynamic but she’s also satisfied with how it ends. The duke says something along the lines of he’ll live one day longer than her so that they can be buried together. Otherwise, they’ll always be together for life and she’s satisfied by the thought of him never abandoning her.
Like girl, I guess….

I’ve seen the novel spoilers and yall, just go ahead and drop the story. There is no redemption arc and the ending is stupid and unhappy.
Talk about miscommunication/misunderstanding trope final boss. ( ̄へ ̄)
