This journal belongs to Jeon Jungkook, elf mage fascined by human behavior and this is my study, based on the story of my friend, Huang Zitao, and the beast Wu Yifan. After a deal with the devil, Yifan became a terrible monster, seeing everything he believed in tumbling like a house of cards. With a bounty on his head and nothing else to call his own, he lived hopelessly. But when Zitao sees something in him that no other has, the two embark on a journey to find the Vulpecula, a mythical land where the answers are kept.
