The Story I Created... For You

Do you believe in the existence of parallel worlds? For a long time, it was nothing more than a mysterious concept to me... Just a theory. Until one day, I woke up and found a strange screen in front of me, telling me that I had been chosen to travel to another world... To save someone from a parallel world. I thought I was dreaming. So I pressed "Yes." But moments later, I found myself in a place that had nothing to do with my world. A world filled with magic, monsters... And a system that granted me the ability to grow stronger. Everything looked like something straight out of a fantasy story. But there was one problem... I had forgotten something important. And I didn't even know what I had lost. It seemed this was no longer a dream. And if I wanted to keep living here, I only had two choices: Become stronger... Or d— Well... Maybe there are other options. But for now... I'll choose the first path.
