An Unknown Place There's a place deep beneath the ground, so far down that no sunlight could ever reach. There probably isn't anyone who doesn't know of it. And yet... I don't know it. I don't understand it. I've never seen this place before. And what's this light shining down on her and me?

An Unknown Voice A girl with a sweet, innocent voice called out to me, asking me for something. Her voice was soft, almost clingy, the kind that makes you want to give the person a pat on their head. It was not a voice anyone would forget. And yet... I don't know it. I don't understand it. I have no memory of what we spoke about... I can't even recognize her voice.

An Unknown Face Her smile meant nothing. There was no intent behind it. It was simply an unconscious smile. That's what made it so unsettling, something everyone would notice. And yet... I don't know it. I don't understand it. I've never seen her real smile, and I have no idea what might be hidden behind it.

An Unknown Gesture The way she opened her mouth was almost like she was seeking affection. She was just doing it on a whim. Anyone would see that. And yet... I don't know it. I don't understand it. She really did look like she was acting spoiled, and maybe... just maybe, I was someone she felt she could be spoiled around.

An Unknown Dream I forget everything. I tell myself I understand nothing. Every assumption is stripped away from us. Every reason no longer applies to us. We're nothing but an anomaly―an outlier. And because it could never happen, it did—a fleeting, innocent moment. That's why... I don't know this scene. I don't understand it. She's the younger sister, and I'm the older one. In our usual place, I softened my expression at her sweet, needy voice. She smiled as I gently patted her head, then brought a piece of cake to her lips. This is... a dream. I know that better than anyone. Something beyond perfect―beyond a perfect ten. A moment I could only ever dream of, precisely because it could never be real. And I know that calling it a dream only makes sense because it's impossible. ...But I don't want to call it a dream. So I tell myself otherwise. This scene... this moment... I've never seen it. That's why I call it... a dream I don't remember. And that's the story I'll stick to.
