Prompt: Write a short story about a man who discovers a magical portal

The day started like any other. I woke up early, got ready, and headed out the door. As I was walking to my car, I noticed a strange light in the sky. I didn’t know what it was, so I just kept walking. As I got closer, I could see that the light was coming from a portal. I didn’t know what it was, but I knew that I needed to find out. I walked through the portal and found myself in a different world. I didn’t know what to do, so I just walked around. As I was walking, I saw a girl who looked like me. I didn’t know how to talk to her, but I didn’t want to leave. Suddenly, a monster came out of the portal and attacked the girl. I ran to her defense and fought the monster off. I was able to save the girl, and we both returned to the portal together. I didn’t know what to say to her, but I knew that I would see her again.
