So I think I am nearing the end of a current update... and I am really confused what is happening... what happened to Ami? Why does she think that her friends are against her now?
Ayane, Maya, and Sensei are trying to keep Ami from finding out about the resets, and continously do things behind her back that she can't ignore throughout Chapter 3.
For example, Ayane "borderline" kidnaps Sensei right in front of Ami while she has to work in Ayane's 'How The World Works' Chapter 3 Event:
Ayane and Maya also seemed to start hanging out without Ami, including at the Shrine:
and basically since the beginning of Chapter 3, Ami made it rather clear she noticed they were acting different:
Even Tsuneyo seemed to pick up that Ayane changed:
Albeit, she's far more perceptive than she let's on.
Overall: This all seemed to translate to Ami thinking that her friends are intentionally leaving her out of things, which well, they were, and they are not exactly good at hiding it.
In which event does Otoha kiss Niki?
The 'To the Future with a Smile' Chapter 3 Main Event.
Who is this old one you speak of?
Yeah, That's "The Old One":
It's shown up a bit:
It was "summoned" in Noriko's 'I Really Want to Stay at Your House' Chapter 3 Event, which if "missed" is replaced by a red 'CONSUMED BY THE OLD ONE' with a line through it.
I somewhat think that the old one is actually just
Pareidolia's original form as perhaps Sensei's imaginary friend from his childhood, but that's just a theory.
