Asking something very minor: does anyone know what Yumi was referring to? Specifically, what event to correlate if there is one?
"project thing" sounds like Yumi's job hunting at first glance, but none of her job search events look like, or are precisely on 11/1.
Besides, their back-n-forth here sounds like this "project thing" is something that happened between Yumi and Chika when they were on school ground. This potentially rules out their little talk about the incoming Shark Tank Battle in
A Frame on a Shelf in a House since Yumi wasn't attending school around that time (even though the date of that event is quite possible to be 11/1). In addition, this will also rule out most of Yumi's events since they mostly took place outside of school.
Due to the nature of this game, it's probably possible that she is remembering multiple things from different Halloween and mixing them up, and the take home message is just Yumi feeling incoherence in memory. But I am mostly a technical person and choose to believe that Sel
is deliberately referring to a specific event (well if not I won't be too sad; it's literally quite minor)
