Story

What the post asked, what the answer turned out to be, and what the chain says happened. The record below holds the data.

Blue

Multiple choice: blue, green, red or yellow. The field is three lowercase words.

The only blue thing on the Wattpad cover is the key, so blue BFUB key on cover. The post said TOMI, the hash says BFUB, like block 48.
