“Felix seemed ravished with delight when he saw her, every trait of sorrow vanished from his face, and it instantly expressed a degree of ecstatic joy, of which I could hardly have believed it capable; his eyes sparkled, as his cheek flushed with pleasure; and at that moment I thought him as beautiful as the stranger.”

– Mary Shelley

Frankenstein, Chapter 13. The monster describes how Felix met and fell in love with Safie and her beauty. He yearns for similar human-like affection.
