@Nep - That's why I said she hasn't opened herself up "completely". I do understand it's common to have no ambition especially for someone her age who is still pretty young, but her relationships with the other maids seem to be pretty superficial. It isn't as heartfelt as her connection with Alejandro; if Alejandro matures a bit more, perhaps he would also feel frustrated that Ibelina is content with watching over him, and regards very little of herself. For lack of a better word, she still gives me an "outsider" vibe compared to other transmigrated heroines. She still feels like she is seeing the world she is in as a "world in a book", rather than "a world she is really in" right now. It isn't as noticeable as Canaria, but I still feel her detachment. Hopefully, with more chapters and character development on her part, it would give some answers.
The cure for the curse is still quite vague and suspicious to me, so I'm going to go with my theory that she is possibly connected with FL's Kingdom. So far, the story doesn't seem to mention lore like that for nothing. And since we still don't have answers for her origins, there is still a possibility for it to happen(not really a fan of too much drama and scheming from convenient plot devices).
