One of the first pages of cartoonist Jane Mai's See You Next Tuesday is simply a large drawing of the girl on the cover winking, with the words "This is my diary, xoxo Jane Mai" next to it. That certainly seems to suggest that the many short comics, drawings and bursts of hand-written text should be read as autobiographical; as real or true. But that page is followed almost immediately by qualifiers.
The first is a hand-written page stating that "The following series of events is not presented chronologically and frankly time does not exist anyway. I'm not even sure I exist TBH." And that is followed by a two-page "people guide" introducing the dramatis personae that star in the book, and... four of the seven are different versions of Jane Mai.
