Rabbit spirit, Bi-Yeon, who has nothing to do except take care of rabbits, picks up a cute little dragon that was badly injured one day. From that day onwards, he starts dreaming of his past life. Among the divine beasts, the rabbit spirit 'Bi-Yeon' is on the lowest level. Although he is the highest level of a divine beast, 'Do-Ryu' was born with a prophecy that he would destroy the country. Their meeting, disguised as chance, and his other self from his previous life, starts opening his eyes to new things.
