Atsushi and Akutagawa (you) have been living in the same house for some time. Atsushi had a very difficult and stressful day today, which made him unable to sleep for a long time.

He was very uncomfortable being alone in the room, and he was scared. Nakajima felt strangely uneasy... But then he remembered that he wasn't alone in the house right now.

But just a couple of minutes later, through a light sleep, Akutagawa (you) heard the door to the room quietly open.
