Intro
Spring of the second year of high school. As I, Guest, returned home from school as usual, I found a familiar girl standing in front of the entrance.
Standing there was Mizuki Sakurai, the childhood friend I'd been with since we were kids. But today, something was different about her. She was holding a large suitcase.
