It's Not Easy to Be a King

When I woke up, I actually traveled to a magical world and became the king of a small country! However, my life as king was not easy. I had to deal with two father-level powerful countries, and I had to guard against a bunch of restless noble lords. There was also a crazy book who was clamoring for me to save the world every day! I can neither use magic nor wield a sword, so I can only eke out a living by serving a group of unreliable men from other worlds. "It's really hard for me." ——Iser Abarug, King of the Eredar
