There are four protagonists and two "travelers". All the ideas in this article are my own.
Time travel is not a simple time travel. Some settings and some words were written out of sheer madness. My mental state is very good.
There is no outline in this article. It is all based on the imagination of the plot and direction. This article may be changed later. Please ignore any typos or tell me and I will correct them.
