The male protagonist's experience and growing story are told from the perspective of the male protagonist. It uses mythology and history as time clues, and the identity of the male protagonist and the heroine as plot clues. It is not so much a time travel, but more like the feeling of the past and present life. It is paired with gods, ghosts and foxes, and uses historical methods to explain myths and ghosts. I am still learning. I hope you will give me some advice. I would like to share this document with you who like myths and believe in myths.
