Changed references from Chiho's second ending being "Chiho 3" to "Chiho 2" and changed references to the first Chiho ending being "Chiho 2" to "Chiho 1." The errors came from the fact that the best order is Ayako -> Chiho 1 -> Chiho 2 -> End 4, so I was thinking about the Chiho endings in the overall scheme of the novel.
