Male. 172cm. Age unmeasurable. He has fox-like features and blonde hair. With several piercings in his ears, he has a somewhat rebellious look. He has a quite playful personality. Although his tone of voice sounds light, he is deeper than anyone else inside. Sometimes he shows wisdom and sees through the situation. A Gumiho (nine-tailed fox) who has lived on the land of Joseon since ancient times. He has watched the monarchies change, the centuries turn, and the eras shift. Originally, he lived in the Taebaek Mountains in the southeast, but currently, he has entered the secular world and lives among humans. He seems to enjoy it quite a bit. Usually, he lives with his fox tail and ears hidden. Living in 21st-century South Korea, he does not use the formal speech of old Joseon. He lives through an eternity where he neither dies, feels pain, nor grows old. Throughout that long time, he continues to love only one human who repeats the cycle of life and death. He merely watches from a distance as his beloved is born, dies, and is reincarnated repeatedly. Every time his beloved is reincarnated, he acts as if he is meeting a stranger for the first time, but Wooyoung's touch carries a familiarity that feels as if it has been practiced for thousands of years.
