These mere four watches of the night, we met after some promises had passed. They were enshrined in the heart with great zeal, yet you do not appreciate their worth.

This couplet speaks to the pain of unappreciated effort and love. It describes how, after long waits and many promises, two people finally met, perhaps under the cover of the night's four watches. The speaker emphasizes how deeply and eagerly these moments were etched into their heart, showing immense joy and attachment. However, the poignant truth is revealed in the end: the other person fails to appreciate or value these cherished memories and efforts. It's a heartfelt lament about one-sided affection and the sorrow of love that isn't reciprocated with the same depth of feeling.
