I Went on an Adventure with the Hero

This is just a clichéd story about a hero fighting a demon king. Behind it, though, lies a tragic tale of a hero. There's simply too much packed into it, making things a little messy.

Aside from a few characters, there are no purely evil people in this book.

There won't be a harem, and the female lead hasn't even been decided yet.

The protagonist has only average talent, with no power to destroy the heavens, the earth, and everything in between.
