But the door that opened… was the room next to Matsuda’s.

Wait, huh?

It was strange. There was no one there. The door was open, and I even heard a person’s voice,
but no one was there.

“Hey, what’s goin’ on? You’re bein’ very noisy.”

Someone’s voice echoed quietly in the hall… and even more surprisingly, it was a kid’s voice. I
looked around once more, but there was still no one there.

“Hey, Big Sis, where are you lookin’? I’m right here!”

“W…Where are you?!” I turned to face the empty hallway and yelled. “S-show yourself!”

Once again, I could only hear a voice.

“Haha, I’m not hidin’ anywhere! I’m right here, in front of you! You just haven’t noticed me
yet.”

In front of me?

I took a deep breath and waited for my pounding heart to calm down. Then, I properly
concentrated on my environment.

That’s when I saw him.

“Oh, did you finally notice me?”
