I don't really like Jeanette but I hope she doesn't turn her back to Princess Athanasia.
This the reason I hate Jeanette:
Although Claude immediately recognized that Jennette was not his real daughter, her genuinely loving personality eventually melted his icy heart. He accepted her as family and allowed her to reside in the Emerald Palace, the official home of princesses for generations. Athanasia, who was still confined to the Ruby Palace, set aside her own desires and taught Jennette the ways of the palace. With her angelic heart and sunny disposition, Jennette became a princess beloved by the entire continent, while Athanasia remained a pitiful princess, unacknowledged by her own father.[1]
When Jennette reached the age of 18, her maternal aunt, Countess Rosalia, devised an elaborate scheme that would ensure her niece ascended the throne. The countess secretly poisoned Jennette's glass and framed Athanasia in hopes of removing her from inheriting the throne, unaware that Claude had never had the intention of making Athanasia his heir. Unable to contain his wrath, Claude mercilessly executed Athanasia by hanging without a trial,[1] along with Lilian York, the sole person at the imperial palace who vouched for Athanasia's innocence.[3] When he later discovered the truth, Claude felt no remorse for wrongfully executing his own daughter. Jennette, however, suffered from extreme guilt and sought comfort in the arms of her fiancé, Ijekiel Alpheus. With his and Claude's support, Jennette managed to put the ordeal behind her and eventually married Ijekiel, living happily ever after.[1] (c).who-made-me-a-princess.fandom.com
