I like that the plot is suggesting that Athy could one day be empress even though she said she had no interest in the throne when she was younger. I do hope we will get to see her in action as the emperor's proxy. My main worry is that we'll be robbed to see this when Dark Claude makes a come back or when possessed-Mr. White introduces Jeanette as a princess.
This is just baseless prediction but I just want to throw my cards out there:
a) Athy will have to use her powers to save Claude - she's currently growing as a character but I want her to do a lot more as the MC.
b) Lucas will go after DarkClaude and fight the evil spirit - this way, we'll find out that the evil spirit is Aeternitas and he's after Lucas all along.
@bimbobimbo even if you get spoilers, the webtoon isn't following the novel anymore. So at this point, anything could happen.
