I'm not sure what novel you're referring to. However, according to the information you provided, I can try to help you find some related novels. The other possibility was the 'Library of Heaven's Path'. This was a story about a fairy. Because the fairy did not want to be found by the Heavenly Emperor, she went to the male protagonist's residence and met him there to experience adventure and growth together.
