Olaf was a genius. This, she realized, watching the snowman struggle, was love. Olaf had been willing to put himself in danger because he didn't want to see her get hurt. Love wasn't the canned romantic declarations. That was nothing but fluff. That was what Hans had thrown at her and what she had mistaken for love. Pure, true love was what Olaf was showing her right now - sacrifice.
Elizabeth Rudnick, A Frozen Heart
love, sacrifice, true-love
