What emotions does Fox Fairy's songs express?

Fox Fairy's songs express the impetuousness of people's hearts and the ups and downs of love. The main idea of the lyrics is that I heard that there is love in the world, and the secret spread to the mountains. The fox is practicing, turning his thoughts into puzzles and finding his heart. How do you know that the road is too difficult, the heart is too fickle, love is not funny, and it hurts people invisibly? The fortune teller pinched his finger and calculated. Don't be unwilling. Love is not funny. Many people died, infatuated and laughing crazy.
