If I had known beforehand that engaging in love would only result in sorrow, I would never have fallen in love.

This couplet expresses a deep sense of regret, almost like a sigh from the heart. It's as if someone is saying, 'Oh, if only I had known that falling in love would bring such pain!' It beautifully captures that universal feeling when our heart is hurting because of love, and we wish we could turn back time to avoid the sorrow. It conveys the bittersweet nature of love, where joy and pain often walk hand in hand, leaving us with a reflective, sometimes sorrowful, understanding of its true cost. It's a profound human experience, voiced with simple yet powerful words.
