The boy who Sneaks in My Bedroom Window

The Emperor had issued an official decree to appoint a successor to the throne—one who would become the next ruler of the empire.But instead of a direct appointment, the successor would be determined through a formal battle among the princes and princesses.A battle that would drag in many factions, overflow with conspiracies, claim countless lives, and reshape the entire continent... was about to begin.But among the contenders, there was one prince who had no intention of fighting—Nolan.Handsome, lazy, and utterly annoying, Nolan was well-known for the many unflattering titles given to him by those around him.Nolan: “Fighting to become emperor? Please... I just want to relax and enjoy life.”Rather than compete, he convinced his twin sister to fight in his place while he supported her from behind the scenes.Nolan: “My dear sister, I leave my future in your capable hands!”And with that, the prince’s journey toward a life of leisure—relying entirely on his sister—officially began.
