I kinda get what you mean, but Jeanette is actually the one who is trying to bring them together, she was the one who brought up getting Claude to bring Athy back to the palace in chapter 67, so they can patch things up, so if it wasn't for her bravery in entering that sensitive topic for him, then Athy wouldn't be back in the palace right now, however I do agree that it's bad timing for her to be all giddy, whilst Athy is having a literal crisis because her dad doesn't remember her, but she just seems to be content with having all of her known relatives(family) together, so it's expected that she'd be a bit happy.
Yah I agree with here I feel that she is very hated much because of the original plot where she took athy's place and replaced her. Throughout the chapters she was shown many times on how much she wanted to help her 'sister' and 'father's reconnect. So sometimes I guessed watching too much drama webtoon can make us suspicious of everyone who is naive and helpful hah!(￣∇￣")
Lol
I know jeanette is good n just naive but I hate her sooo much u guys keep defending her saying she’s just naive n happy go lucky but is she really ? I know she just wants a family but athys father lost his memories of her n jeanette just walks up to him like “hehe here’s some chocolate hehe” even though she’s athys friend n she knows that athy might be sad that her father has lost memories of her like... it’s not a good time to try to reconnect with ur family Skksdjdk I feel like jeanette is trying to replace athy cuz of this. I feel like she knows what she’s doing
