I agree and disagree with you, the novel is different from the manhwa so idk what direction this is going but in the novel jeanette wasnt the best person and was very jealous of what Athy had. She even hated that the white haired dude liked Athy and not her so from the novel alone I dont like her so I really cant like her cause of the bad vibes she gives.
Tbh Jeanette mostly just gets on my nerves at times because she’s kinda in the way of Athy and Claude, which sounds bad but yeah. I feel bad for her, but it seems like in the past life she chose her original father/creator over Claude which ended up leading to his death (according to one of the flashbacks) which kinda made me dislike her more. Of course I hope she has a happy ending since she seems pretty okay so far (hopefully her jealousy won’t ruin everything), not really with her biological father though since he’s pretty shitty from my point of view. He doesn’t care as much for Jeanette as he pretends to, since she’s just a pawn that will help him bring down Claude.
I personally don’t really think she fits in with Claude and Athy either as close family, since Athy seems to be on edge around her and I’m pretty sure Claude just puts up with her since she takes away the pain/headaches and stuff. Maybe that’ll change in the future though so idk, but yeah this was a long rant sorry about that lol( ̄∇ ̄")

I don't understand u guys
Jeanette is a young thirteen year old who is naive and extremely optimistic and lonely of course she would think blood ties and family will resolve her loneliness
She can't go out much because she isn't allowed and so can't make friends
Her only options to find love are ATI and Claude
She feels as though her adoptive family don't love her
her love tank is not fill
My heart breaks for her I hope she gets to have a family she loves someday
I hope her creator/father or whatever he is chooses to live happily with her
Both deserve to have each other's love
