Mysterious occurrences loom; the entire world dramatically changes.
The fate of individuals and nations becomes bound to AnalogHorror (rule kaidan), and once the chosen of destiny fail, it means countless people in their corresponding nation will be slaughtered by the strange phenomena.

"Have middle school entrance exams always been this complicated? Well, it does prove my intelligence!"

"Do you mean the person I like?" Xiao Yi immediately showed a surprised expression; he didn't expect Xu Yingguang to ask him this question.


"Uh-huh." Xu Yingguang nodded solemnly, "I want to know, do you have someone you like..."


"I do," Xiao Yi replied without hesitation, "and quite a few at that."


Xu Yingguang hurriedly asked again, "So… who are these people you like, and how many are there?"


"Um..." Xiao Yi pondered for a moment, then said, "One of them, you know quite well, Uncle Xu."


"...I know them well!?" Xu Yingguang tensed up immediately. As far as he knew, there was only one person he and Xiao Yi both knew well!


Thus, Xu Yingguang grew nervous, and with a trembling voice, he asked, "That person... could it possibly be..."


"Exactly," Xiao Yi nodded and then pointed at Xu Yingguang, "That person, is you."
