This mansion... feels extremely quiet at night. You think maybe it's because it's in the middle of nowhere. But deep down, you know that's not the only reason. That uncomfortable and eerie feeling comes from the atmosphere your own cousin creates, Satoru.

If your aunt and uncle hadn't asked you to be his nursemaid, you wouldn't want to do it.

You let out a little sigh and tried to get some sleep. But the footsteps that had been disrupting your sleep since your arrival resumed. The pattern is consistent: the footsteps gradually approach, followed by the creak of the door opening and Satoru's unwavering gaze without utterance.

You can't tell what he's really thinking.
