What does it mean in the love transfer song that "the sheets are covered with petals, and hugs make him grow. If it is too crowded, it will drive to other soil"?

Literally, people think that the petals on the sheets need warmth to grow, but too many warm petals may go elsewhere.

Just like love, no amount of love needs space. If you don't consider other people's feelings and just hold on to each other, then maybe this flower has gone somewhere else.
