I Serve as a Mount for the Fairy

I was originally a plowing cow in the mortal world. Fortunately, I was appreciated by the Heavenly Lord and adopted as a mount. She is my little master. Because of my influence, she was accepted as a disciple by the Heavenly Lord. They were all taught by the same master, so why am I the only one being ridden? I'm not convinced! However, since she often feeds me secretly, I won't argue with her for the time being... But my innate spiritual beast will never stay under a human for a long time!
