"If two people sign a contract with black and white on paper, then naturally it can't be done like this.
Because, the content of the contract cannot be written on the back of the paper; this is an established tradition.
Moreover, usually, contracts are made in duplicate, or even triplicate if a third party is involved.
However, magic contracts are different.

Therefore, when signing a magic contract, it requires only one contract magic scroll.
The content selected for the contract in the contract magic scroll is what is chosen for these pieces of paper."

A single magic scroll allows the specific content of the agreement to be selected and attached to ordinary paper without content.
