I’ve been trying to find this manhwa for ages, but no one seems to remember it.
The main character was married to a duke. She thought he didn’t love her, and she also thought the maid and everyone else felt the same. She died and got reincarnated as a child. I’m not sure if it was in another child’s body or if she went back in time to her own childhood.
A memorable scene is when she thought her husband hated her and would be fine after her death. But she saw him in his bedroom, crying about her. She was like a ghost or an illusion and thought he couldn’t see her, but he did and shouted her name. Then, she was suddenly back in her child body, at a kid’s party.
It’s not “I’ll Just Live on as a Villainess” or “The Duchess with an Empty Soul.” I think the duke had either white or black hair, but I’m not sure, so sorry if that confuses things further.
