The resets according to Maya were mostly the same in Chapter 1, except:
- Ami never became a maid.
- Maya never got that scarf.
- Maya may not have been having Upside-down dreams prior.
- Kaori and the Shapeshifter may have not been around.
- Yumi presumably never stopped him from walking into static 3 weeks in, like in this timeline.
- Sensei seemed to be more irritating, curious, and compassionate in this timeline, based off Maya's reactions, which probably affected Maya and everyone else, in this timeline.
- Makoto may not have Blue Jayed, as Maya didn't seem used to Sensei even being on the roof outside of resets, let alone with someone else.
- Things post Chapter 1 (like the school being swallowed) never happened, Sensei rarely ever made it to Winter, and never past the 3rd Reset (the first time Ayane made it to the roof and didn't survive).
Sensei was also apparently switching personalities and raping people far more often, and he apparently died a few times, was broken by Maya a lot, and sometimes failed immediately in his "new life", so Maya created that Journal to help him a little.
Also if Psycho Ami is a thing, that probably happened a lot because I guess Maya kept trying to tell Ami for centuries of resets apparently, before giving up.
The creepy Yumi detentions were likely pre resets, and he apparently did stuff like stare at her and stalk her:
Sensei seemed to have a lot of lust for her:
As for Maya, pre resets, I doubt she considered anyone besides Sekai, Niki, and Noriko, as a possible threat when it came to Sensei. The big titted bully probably wasn't worth her time. Ironically, Yumi may have reminded Sensei of Niki, based off how he compares the two:
USER2/Wire god talks like this:
That was likely Pareidolia who was comparing Sensei to Sekai, and Yumi to young Sensei, since it was in lower case which is a habit of it's. Pareidolia seems interested in Yumi's family, with Kaori possibly being it's Yasu.
Most Yumi things seem to reek of Pareidolia, tbh. He even forced Sensei to blurt out he wanted to fuck her in Yumi's recent 'Frog Boy' Event:
