In the ancient practice of sending messages through a bearer, people would write secret messages in a substance that would only be revealed on plain paper through the use of a reagent. For example, lemon juice is normally transparent on paper, but when heated, it becomes brown and any message written with it can then be read.

The recipient would then have to treat the letter and read between the lines of the letter [빈칸 추론]
