Fridge / Shihori Escape

Fridge Horror

• In the True End, it's revealed that Kitarou murdered Shihori and had been keeping her corpse in his bed. What exactly was he doing with the corpse?
• How long had Shihori been dead? Surely, if she had been missing for a few days or longer, someone would be looking for her. Would they ever find her or would she be lost forever?
• With the True End, it reveals that the breakup was completely reverse. Shihori broke up with Kitarou instead of the other way around. What other delusions did he have?
