Just Theory
I think dahye is shannon, its like the manhwa called " the reason why realiana ended up at the dukes mansion"
It might be that Dahye is Shannon's reincarnation, as Shannon had a good ending the first time so it wouldn't be weird.
It would make sense as Dahye doesn't recognize herself as Shannon, also since she was the one called into Violet's body and not anyone else.

Shannon's soul is sleeping in her body. It will awake in 20 to 25 chapters.
So... both Violet and Shannon are in Shannon's body...?
Yes
Oh wow, thank you for the spoiler!
...where is the real Princess Shannon? Is all I could think when the revelation was out. Is she in Dahye's body???
I also lost all of my brain cells reading this, but I can't stop I'm too invested now and want to see the ending ooop
