How to write two small-scale copywriters?

This copywriting method is as follows:

Two little cousins are inseparable, wandering the rivers and lakes together. They are close friends like brothers and partners who support each other. They share their laughter, get through the difficulties and pursue their dreams together.

They are fearless and walk together, and they can find each other whenever and wherever. Their friendship is rock solid. No matter how the wind and rain attack, they can rely on each other to tide over the difficulties together.
