True love, in the simplest term that I can think of now, is putting the needs of others before your own. Not a kiss. Instead of running for that kiss to save her, Princess Anna risked her life to save her beloved sister. That’s true love.
True love has so many kinds, and can be expressed in so many ways, not just romantic. And true love knows no gender or label too. That’s true love. Princess Anna did not run for a man. She ran towards her sister.
