Finally duke Artian really joined the story.
Strange that he looks so cold compared to Lidusis. But in this chapter it seems the he really cares about Lidusis.
He said "It feels as if I'm still having nightmares". It seems to be very important to Lidusis' childhood..
I think that some time ago duke Artian found out that Lidusis will die sooner or later.
That's why he was avoiding Lidusis and prioritized his older brother - to avoid being hurt by Lidusis' death.
But in the end it turned out that his older son is brat and bully but his younger son is really gentle person despite all the neglecting...
Any more ideas?
