Huli De Xianjing

The human girl Chiyin kept having nightmares about foxes. Until one day she finally met an actual fox spirit, the nine-tailed silver fox Yinran who only had eight tails. To take back his missing tail from Chiyin, he had to fulfill one wish from her. Chiyin didn't want anything to do with him, but the sly fox kept intruding into her life, as his tempting face manifested in front of her. "Would you like to make a wish now?"
