Comment by Sese Chan on Who Made Me A Princess - Chapter 61

I'm guessing you mean like what happens. So here's what happens btw Claude gets healed and gets his memories back. 

so as we know Lucas went to the tree. Well he brought back a piece of tree for another reason. It's explained that Lucas is undying so he can't die. So he brought a piece of the tree to give to Athanasia so she can live with him forever. So in orders for that happen she has to eat or something like that. But then Lucas says that maybe the piece of the tree can save her dad. Because the Wrold Tree is the universe every single past lifess and future life's it's all of that and for Claude's memories to be healed she would have to in to the tree and find the curse. But since there's so many thoughts in the world tree if she loses herself she won't ever be able to go back. So that's why Lucas prevents her from going but he ends up letting her go. So I don't wanna spoiler what happens next cuz it's kinda cute but that's pretty much what happens. 

i spoiled so muchhhh
