A Sad Song for a Departed Lover

The narrator chose to turn their back on everything in the world solely for their lover. However, the lover, knowing this sincerity, laughed and shattered the narrator's heart.

Left alone, the narrator suffers from resentment and regret for the departed lover. The longing that overwhelms them every night has become a great pain.

Pointing out that the other person dismissed sincere love as a trivial matter, the narrator predicts that when lonely nights come, they will realize the narrator's absence.

The narrator reminisces about the precious time spent holding hands and walking with their lover in the past, regretting those feelings.

In the changed circumstances, the narrator asks the other person not to return and hurt them again, and instead of erasing memories of the lover, tries to come to terms with it by remembering them with a smile.
