Very nice twist, which actually works because the idea of an actual person approaching a “singular document” that would fulfil his purpose is so intriguing.

Even though the intent at the end seems humorous, there’s still something quite melancholy about the whole thing.

Quick suggestions:

“in vain” rather than “in vein” and “by random” at the beginning doesn’t sound quite right to me. I think just “randomly” would be better, but I may be wrong.

Cheers, changed the spelling, but once I’ve published a story I don’t like changing the structure too much. Just one of my ways of trying to help discipline my writing.
