What does this girl mean by a loyal wife?

After all kinds of difficulties, I finally saw hope.

The literal meaning of girls saying "faithful wife" means that only those who can persist to the end can see the rainbow, hope and victory after the storm. This is a positive and optimistic spirit of persistence and never giving up, and a positive attitude towards life. It encourages people to have firm faith and persistent perseverance in the face of difficulties and setbacks, and believes that efforts will always pay off.
