Before a transaction is made, profit is the purpose of the transaction.
While the transaction is in progress, the interests are ranked first.
After the transaction is completed, the interests should stay aside, and the lover is the most important.
For their own benefit, they made a deal and got married. The beginning of a transaction is also the beginning of marriage, but not the beginning of love. The end of the transaction is not the end of the marriage, let alone the end of love.
Intention: 1 to 1
