It's possible for her to have more than one sibling in that world. It could be the emperor. But if he is, something def went down that made him and Ludan become estranged and hate each other's guts. Or maybe they don't even know they're siblings?? The emperor is a secret love child??? 😲
But if the emperor is the lil sis transmigrated into the emperor, and she somehow knows the pope has her older sister's soul, whats up with that temper?? Maybe MC is
SUCH a sis-con that she glossed over her younger sis's psycho tendencies and only remembers her smiling face (maybe she's even mistaken about how she receives the sis's heart, and it actually wasn't a loving, selfless act of kindness). MC paints her little sis as an angel, so wtf lol. I know 20 years is a long time, but this change in personality is wayyyy too drastic. To kiss her older sis immediately after she wakes up, and to unleash chaos and hell because the sister's soul doesn't recognize her... without even saying who she is....... naaaah, I wouldn't say it makes more sense that way.
It
could be an interesting little twist though, if written well. But right now, too many doubts. The story is still young though, so we'll see.
