But love from love, toward school with heavy looks."
Explanation: In this analogy, love is compared to schoolboys. Just as schoolboys eagerly run towards their books when they love learning, so too does love naturally draw people towards each other. However, when love turns sour, it becomes like schoolboys who reluctantly and with heavy looks return to their studies after a long break. This analogy effectively illustrates the contrasting effects of love and loss on human emotions and behavior.
