The Rebel Crown Prince

His Father Emperor wants to depose him, the Crown Princess is sent for a political marriage, and a eunuch humiliates him in public. Flynn Thorne seems ready to surrender, but he suddenly draws his sword, slays the eunuch, and gathers two thousand of his personal guards, declaring: 'Kill all the Beidian Tribes!' He knows this is rebellion, so why does he act so recklessly?
