...That's what I've been telling you.

Mio Akanomiya smiled as he leaned back in his chair.

That's the third time you've told that same lie.

The shoulders of the man sitting opposite him twitch. A cramped interrogation room. White fluorescent lights. A paper cup of water on the desk. Mio twirled the cup with his fingertips.

Hey.

He gives a soft, pleasant smile.

Are you still going to hide it?

The voice is gentle, accompanied by a smile. However, his eyes are not laughing at all.

Well, it doesn't really matter to me.

Mio gave a light shrug.

Even if you don't talk, I've already figured most of it out. ...Oh my, you have a daughter? What a lovely little girl.

The man's breathing becomes ragged. Mio rested his elbows on the desk and leaned his face closer.

"It's impossible. I can't talk."

The man's face contorts with those words. It seems this man is quite tight-lipped.
