Judging from the commentary and the time this was posted on Twitter, I don't believe this is part of the "Forgive Me Mari" story, so I'm removing it from pool #23359. Shame, as it actually fits rather well when placed before post #8291026 because of the mood whiplash of a happy memory followed by depressing reality.
