I want to do it over.

I lost the war, my country was destroyed, and I alone survived. Having lost the woman I loved, I wandered from place to place as a mercenary, seeking a place to die, when a man spoke to me. "Hey there, buddy. You've got a charm spell cast on you. And it's a really strong one too. Want me to break it?" A charm spell? What is that? That meeting with that man changed my life. I go back in time and change the future. R15 is a precaution due to scenes of death. This is an original other-world story.
