The writing is new and there is no fixed CP. The protagonist is a genderless god. He has different identities in different time and space. Therefore, he is sometimes a man and sometimes a woman. He will not remember his past life in different time and space. For him, a new identity is a new life. The lover in each life is not the same person, but every time he will accompany them through life and each life will be the only one in his life.
