Me Who Traveled Through Invisible Anime

In a certain apartment, I was lying on the bed. I hadn't slept all night. My brain was still excited. The sun was shining in from the window and my eyes hurt. I got up and closed the curtains. This is the second day. As long as I persist for three days without mental deterioration, I can return to the original world as agreed. I turned to look in the direction of the door and was stunned. For some reason, my brain has not been normal since I came to the world. There is always an expectation in the depths of my mind, as if I am looking forward to what will happen to me when I am forced. I don't know if this is my own idea, but it really feels good.
