Love is sweet at the beginning but can also lead to pain, as hearts may become fickle when tempted by other smiles or charms. While love may stay for a time, its nature is to come and go freely as fate or fancy dictates, longest when unhappy and quickest when forced to remain. Just as it's impossible to bind the sea, flowers or birds, so too love cannot last if caged and captured, as it requires freedom to renew itself through fresh beauties.
