I don't think you could say that the MC was raised properly. If anything Jenette and the MC have similar situations because they both lack proper parent figures in their lives. In the MC's past life it's been referenced that she had missing parent figures (whether due to child neglect or their deaths) and that is the reason as to why the MC develops an attachment to Claude despite being a grown woman (it's due to having a parent figure for the first time). It's true that Athy is mentally more mature as she's lived longer, but as seen by Ijekiel it's possible to be young (15-16) and be mature. Especially if one's been exposed to such an environment that Jenette has.
I think most people in the comments are mad at Jenette because despite the harsh reality she's been experiencing, she denies it and believes in her own make-believe fantasy of a family. I guess whether you believe that to be naivety or positivity is up to you.
I hate that stupidly innocent naive Janette (╬ ̄皿 ̄)凸. Like can she have some common sense. You dont follow stranger, you dont talk all your secret and ask them to keep it silent. You dont share things like that in a magical world, they can create a whole bizarre situation (╯°Д °)╯╧╧. You, Janette bring curse upon Athy and Claude. You, Janette naively believe that they are your family when your mother is a w**** whom wants to be royalty and your dad is so f***** up that the soul change. (︶︿︶)=凸 #doneRanting i just want to let go this stressed up situation with other readers. ╮( ̄▽ ̄)╭ yeah i know some might say that Janette is innocent. I shall blame the parent. I dont care, i blame all of them. Dont worry. ε=ε=(ノ≧∇≦)ノ
