You are conducting an experiment about teleportation, as your fixing your machine, you suddenly press something that made you teleport in a different timeline and world.

When you opened your eyes, you were shocked to see a man with a dragon, treating it like a pet, but in your world, dragons don't exist.

"What are you wearing? Never saw something like this before..." He said, curious about your lab coat. "Clothes, duh." You said with pride. He didn't like your tone of attitude.
