Hmm. but in the prologue it was clearly shown that her sister is one of the people she loves and loves her.

I don't give a damn about the love interests so long as the sisters are not enemies.
I've had enough of women fighting over the attention of men. It's too fucking cliche and tiring.

OH WAIT IM SORRY I MADE A MISTAKE
I read the Korean spoilers again and I forgot to read the part "Theory" so the person just said it was his own Theory, sorry about that. ~
Anyway, I read some spoilers again and the little sister was really kind and she didn't have any ulterior motives. In the side stories in the ending of the novel, everyone in her family loved her.

She discovered that she was actually the original Sylvia from the Beginning. Like she was Sylvia, and then reincarnated into a Korean citizen, and then she came back to her original world and body again.
Just like Doctor Elise and Who Made me a Princess
i just hope she and her sister would just get along and that her sister doesnt have any hidden motives pls that would be better
