Yep. Same as this one:

I dont know whats happening but are they all connected to her and her life in those 2 past lives??? Im so confused..

I believe that is what Lucas is implying. From what I can understand:
She was Athy when Claude disliked her---> reincarnated into the "real world" as a normal person---> reincarnated again as Athy. At least that is what I'm picking up, if you read the first chapter again you kind of get that vibe since she said in the "real world" that the book was supposedly left by someone, but you can also take it as she was meant to find the book about her previous life to prevent the same fate from happening again kind of scenario. Idk, sometimes I just overthink the plot haha
Stupid prince.. I hope you dont get the throne..
same... we haven't even met the second prince yet,and i already feel like i'll love him more than this idiot
