Stepping away from the door to minimize the chances of their being overheard from the hallway, he goes to stand near Kidou's window and peers outside. From here, so much of their street can be seen. The view is suitable for someone like Kidou who takes notice of so much. And yet, somehow, he hadn't found Fubuki despite living under the same roof as him. Why is that?

"Why do you think we didn't recognize each other?"

There is no accusation in his tone. This is something Fubuki realizes is beyond their control. But it's nevertheless something he's been pondering over.
