No no it's been confirmed that the life Athy lived where she read the novel aka the Asian country was indeed Athy in her 2nd life. Her first life was the life in the novel, 2nd the Asian country and her third is now back to her "past" original world, but a do-over. I forget how it's all tied in with the book but it has to do with Artenitus.
Also Athy doesn't know what happens after the book ends and Jeanette stays with Claude. She doesn't know that Anastacius returns and they kill Claude, all she knows is that Claude and Jeanette stay happily ever after. But you're right that she needs to be more cautious of Jeanette since she knows she's a ball of walking black magic. Luckily Lucas is there to point all these things out but really I think Athy over thinks a few things and then undermines others.
But yes, you're also right in that he was under the effects in the first life. I forgot about that. I mean in a way it's hard to tell those around you about novel worlds and black magic children and stuff like that lol I think Athy is doing the best she can, I actually like that she's a little dumb and not all-knowing and calculating bc that's not her personality.

Holy fuck! 3rd life? No wonder she a lil slow. Too much to remember lol. Hmm I think she should have told them that she had a dream that yada yada yada happened. She should have hinted Jeanette at least so she goes away from daddy Claude lol. Like let's be friends/cousins from a DISTANT. (๑•ㅂ•)و✧(≧∀≦)
Honestly i like Jeanette. My first time liking a potential villainess, and also hoping for the best of her. She's a wonderful and precious child. She only wishes to have a family, to be happy with Claude and Athy. She doesn't mean any harm, she only wants to have a family who will love her, because she wasn't able to experience one. I hope she doesn't end up as the villainess. I hope she also find her own happiness in the end. I hope that her real father will come to love her. I hope greed and jealousy will not eat her heart and soul away.
