Sarah, I'm Sorry: Welcome to Our Galaxy

What if those tragic events never happened? What if no one was sick, no one had an accident, and everyone lived a normal campus life?

If only there was a world just like Sarah’s wish... When Sarah opens her window, another window appears, and she discovers a different world inside, a world with an exciting campus life that she had always dreamed about.
