Who in the Bible is first reported as having fallen in love?

Adam with Eve


"When G?d created Eve and presented her to Adam, Adam exclaimed: "This time, bone of my bones and flesh of my flesh! This one shall be called 'woman,' for she was taken from man" (Genesis 2:23). Spontaneously saying "this time," he expressed his delight and emotional arousal - his love at first sight - for his newfound mate."

Nowhere in the Biblical quote given does it say Adam was in love with Eve. Someone has just chosen to interpret it that way. I'm not sure we have the answer yet.
