different format idea
I just thought of this but thought it could be cool.
There's another group of however many friends. The narrator is actually the future child of one of them, unrevealed, and their future partner, by default also unrevealed, until the end. By not knowing which main character, it wouldn't feel so heavy-handed, and add the fun of trying to figure out which one they were referencing (that would require careful planning to pull off but could be done... again)
