No longing for worldly pleasures, when the boat is filled with water. A perfectly matched pair, both their cherished hopes undone.

This couplet paints a picture of a well-matched pair, perhaps a couple. It suggests that their troubles don't stem from a pursuit of material pleasures or indulgence. Instead, their "boat" is filling with the "water" of profound emotions and unfulfilled desires. Both individuals, perfectly suited for each other, are equally burdened by shattered hopes and unexpressed longings. It speaks to a deep, shared sorrow where external circumstances might seem fine, but internally, their emotional world is overflowing with disappointment and unfulfilled dreams.
