I tried to sort through the timeline to confirm when they met, and Kaburagi-san said it was when they had just come from the countryside... I was being held back by the 15-year lie... They've been in contact for quite some time...?!
Also, Ai is a year older, but Kamiki has been in the entertainment industry longer, right?! They were in completely different positions.
Sorry, I'm a novice.
But I wonder if the dome meetings started five years in advance.
If they did, that makes sense, but if not, then the timing of the Himekawa couple's suicide that Kamiki and the president mentioned doesn't add up.
