So this happens in the side stories when Leo goes to academy
Spoiler!
When Leah was born, there are so many rumors about the change of successors since Leah also has the Boreoti attributes, black hair and eyes with fangs. The nobles who were against Leo spread this rumor while the Northerner remained unbothered cause they already accepted Leo as their future master. Marquis Pardus and Lupe then told Leo not to listen to those scaredy cats. They don’t want Leo as the next Duke cause she’s scarier than Phileo and more vicious than him 😂
They told her to just keep on going cause they like their future ruler strong. Leo was still feeling guilty cause she felt like she robbed her sister’s seat. But she also said that she can’t give up the title so even if many are against, she won’t listen. And because she couldn’t give Leah the Duke’s position, Leo will give her something that wasn’t given to her in the book, a sister's love. So she pampered Leah like crazy. When Varya asked Leah who she loves the most between Leo and Phileo, Leah immediately said her sister 😁
Leah also learned Leo’s habit. Whenever Leah said something kid’s shouldn't say she’ll put the blame to Leo and said her sister taught her that. Phileo and Varya got chills cause it was the same reason that Leo give when she was young (whenever she say bad things she’ll blame the orphanage) Leah would often cry every time Leo will go to academy. Leo being Leo, she also cried along with her sister and drop on the floor while hugging each other. So Phileo very stressed because of his two girls. Leah, Phileo and Varya sent Leo in the academy.

I like to post spoilers for the stories I find interesting because I don't have much time to read novel due to busy schedule
