What does it mean to have a crush on a flower?

Description: Grass grows all over the world, so why be persistent because of that flower?

This sentence can be understood in two ways:

1 means that men and women don't need to stick to one side, and there are many people who can be loved or worthy of love.

There are many opportunities in the world. Don't focus too much on one thing and don't know how to be flexible.

The first explanation is often modern.

Extended data:

"There are plenty of fish in the sea" comes from Su Dongpo's "Recent Flowers", the original text is:

Su Shi regretted that spring could not last forever, singing "Flowers wither, red apricots are small" and "There is less cotton on the willow branches". How many years have passed, with the passage of time, I don't know who added "why do you secretly love a flower" after "where the grass grows in the sea", which became "where the grass grows in the sea, why do you secretly love a flower" and became the best cheering slogan for future generations when they were lovelorn.
