The Brave Man Who Saved the World

[Western Fantasy + Road Story + Slow Heat] I was summoned to another world. The stereotypical king and princess are in. The stereotypical brave team is also there. Dragons and elves are also there, as are the demons. But the only thing that's gone is the villain. The Demon King was defeated just last month, and the former hero has been teleported back. Then what are you here to do? Since I have to wait ten years before I can go back... Then why not see this world with your own eyes.
