Yueru, the princess of the Yinling Realm, fell in love with the Monkey King when she first met him. She had a wish to play with Sun Wukong for a few days, but after Sun Wukong became a Buddha, no one could find him. Her father had a treasure called the Moonlight Box, which no one could touch, so she kept trying to please her father, "I finally got the Moonlight Box, and I can go and play with the male god."
