UGH I LOVE THIS A LOT
is there a novel for this?

The Novel:

So far the translation is only at the Knights Arc, though (so it's at the same part as in the manga).
There's spoilers about the rest of the series, though. (Which I know because I've been sharing them.) Including scenes from later in the series.

That dark shadow is such a fucking manipulator. I'm not surprised he got to Anastasius that good cause it looks like he started brainwashing him when he was a kid. Remember when he was just staring into space out in the garden when Claude saw him? Poor kid. And with his mom being all desperado on him about being emperor, pressuring him and shit, he became an easy target. He probably just wanted love. That's why for a brief second you see moments of him being swayed by Jennette’s kindness.
Well, I'm rooting for our precious Luka. I get Laura’s side but I also get Luka’s side. His best friend just suddenly started avoiding him out of nowhere and he doesn't even know what he did wrong. Did she hate him for his power? He doesn't know, and he was being overprotective because she was just in immediate danger.
