"Hero who saved the world. Yeah, that's what they called me. But look at me now, about to die of old age. The only thing I ever wanted was to be like everyone else. But no, I had to be a hero. I guess that shows you how the world works—after defeating the Demon Lord, everyone forgot about their greatest hero."
"I wish I could have just had a regular life."
After the old hero lay down on his bed, he passed away, never having lived the ordinary life he longed for. Or so he thought. He was enveloped in a strange light, and when he opened his eyes, he was in an unfamiliar place.
"Huh? Where is this? What's going on? Is this the afterlife? Where is God? I want to ask him why he made me a hero."
As he stood up, the old hero noticed he was much younger than before.
"Huh? Did I become younger? Maybe it's because I'm dead. They always say when you go to heaven, you look young again. Maybe this is what they meant."
"Gongseok, come for dinner!"
"Huh? Gongseok? Maybe the lady is calling someone else."
Suddenly, a sharp pain struck the old hero, and he was flooded with memories he had never experienced before.
"Ahh! What the hell was that? And what are these memories?"
After a long time pondering, the old hero concluded that he was not in heaven. Instead, he had been reincarnated into the body of Kim Gongseok, a high school student.
