Yeah, she is more mature because she remembers her past life but that does't mean she will become a genius because of that. In her past life, she is just ordinary boring girl you can find anywhere, neither beautiful, brilliant nor talented. She is different from another main character in Reincarnation story that having advantage from their past life knowledge and quite useful in their new life, like Sang Hee who master ancient (Korean) language, Elise with her medical skill and knowledge, Raeliana & Latte with their fortune teller, Feng Yu Heng with her medical and martial arts skill, all of them somehow end up in unfortunate situation and striving hard to survive. But Ariadna world all completely different from her past life, nothing she study from her past life are useful in this new world, and not to mention she has it all, Beauty, Fortune, and Love, though she encounter assassin but her life isn't revolved in dangers, after all she is a Crown Princess of the greatest empire in the entire kingdom.
Well what more can she do. Her father denies her in learning sword fighting and anything that might seem dangerous or difficult for her. But if you pay attention she learn things very quickly at first glance. The difference now is that she is in a child body so she tempts to over think many things. Like "I know I'm a grown up and sh*t but should I act and think like one or be a child with a mature mentality" I'm just trying to put myself in her position and in my case this story is well done. Not so much drama and we can see how the character develops
Yep, I do. Though Caitel and Asisi seem like strong shounen charcters, the way the story flows shows that that their role is providing a safe and loving environment for Ria to grow up in, and to show how the warmth of having a family and experiencing love can change a person. That's what the whole story is about.
So instead of taking advantage of the fact that she's "more mature", and learning everything she can get her hands on, she just plays all day and never wants to do anything new, always with the same comments and a closed mind...
