Realm

In addition to human beings, you think there is another kind of "non-human being" in this world. It has been with me since I was born. It told me that if I could let him replace me, it could give me anything. It was powerful and special. It told me that it still has one year to live. If it does not succeed in this year, it will disappear. Of course, if it succeeds, I will disappear. This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
