, In the novel, it mostly focused on LucasxAthy scenes, however, in the manhwa it showed more father-daughter relationship with family love and all, but in the novel is different, it's Romance between athy and lucas.
Also, when Lucas came back from the trip to the world tree, he cured Claude as soon as he came back. Jeanette also isn't AS annoying as she is in the Manhwa. And also, I didn't finish it yet but people said that Athanasius isn't really that big of a villain in the novel, it was another character who was the main villain.

who was the main villain in the novel?

I didn't completely read it yet so I can't give an answer to that. (I only said that because I read spoilers on Novelupdates). Also, the "Dad is asleep" Arc in the manhwa is taking way too long compared to the novel

Ohh! I see, thank youu(≧∀≦)
