The Eccentric Middle Child of the Royal Family

Chase is said to have middle child syndrome. He likes to gather attention by wearing garish clothes, squabbling with other nobles, doing dangerous things like riding horses on cliffs, and throwing tantrums over small things just to gain the attention of his King Father, who seems to favor his four other siblings. It led people to hate him. That's what Julian learned from his system after transmigrating into the body of the illegitimate third prince of the Laurier Royal Family. When he thought he already had it worse, his system added, "The danger level around the third prince is ninety percent, which means ninety percent of the people around the prince want to kill him. Please exercise caution." How could he exercise caution when he'd already been targeted right after he transmigrated?
