Xander was speechless when Maxim left his study. All the time they spent in study; he wasn't given a chance to defend himself. He wished that he did because he could tell just how angry and how Maxim was restraining himself. He didn't want to make Maxim his enemy, he was just too strong and most of the people who came to his kingdom were all influenced by Maxim.
Seeing that Maxim came to warn him face to face meant that the other wasn't planning on doing anything drastically but at the same time, he had just lost his younger brother. It wasn't a secret that he hated the other when they were growing up.
His father really liked Maxim a lot even though he kept a blind eye whenever Maxim's mother was doing her tricks. To make sure that Maxim will never become the next king as his mother was a concubine and not the official wife, Maxim as the other son apart from Xander was given that title of a Grand Prince.
