There is a desire that someone would remain faithful, but if their heart itself does not wish to, what can anyone do?

This couplet captures the quiet helplessness of love with tender honesty. We all deeply yearn for loyalty and devotion from the one we cherish, but the poet gently reminds us that the heart cannot be coerced. Loyalty is a voluntary grace of the soul; if someone's heart simply isn't in it, no amount of longing can make them stay true.
