"Our Sweet Love"

In the third verse of "Our Sweet Love," there are the lines "A precious love like this can flower / There's nothing in this world like our sweet love."  "Flower" at the end of the first line rhymes with "our," so that "sweet love" sort of stands by itself, and structurally, this mirrors the sense:  the "sweet love" has no rhyme and no complement because there is "nothing in this world like [it]."
