You settle down at a desk with a maths textbook and read through the material.
Between the equations and their corresponding algorithms, you can read little reminders written by Sydney on sticky notes. The most prominent is one date: November 12th, 2023. It seems to hold some importance to Kylar as well, if the doodles of the outcast all over the notes are anything to go by.
You feel like you should inform Sydney of the doodles the next time you see them.
