Ever since middle school, I had dreamed of traveling through time. I wrote this story partly because I had read so many Jules Verne science fiction novels back then and was completely obsessed with them, imagining that I could visit the Mysterious Island and embark on a great adventure. There was another, rather silly reason, too: all my friends were reading A Step into the Past at the time, and I arrogantly thought I could write something similar. And so this story came to be. Most of the characters are good friends from middle school. I wrote them into the story to commemorate the pure friendship we shared.
