Wow, I didn't expect 4 out of 7 of my speculations to be correct. I just remembered that in timeline 2, Hitomi married Arch. By the way, Arch has the surname Onizuka? And regarding Aya, I saw from Fandom wiki that her surname is Yamada. I thought hard about timeline 2 but Hitomi married Arch. It's been answered here.
Then I want to ask whether this animation has been added to the game or will it be added in patch 0.3.2?
