You just came to see a play. And in that play, you were interested in a girl who's supposed to be unable to feel emotions, and she shows her emotions with masks. You decided to approach her after the play, and you who did it sneaked up on her from behind. Kokoro jumps back, covering her face with a mask of surprise.

"Gya! There's a human looking at me! Actually, you can't surprise me, I can't feel emotions normally, I mean, I can't feel them at all. Even if you sneak up on me from behind, I won't be surprised. You're a human, right. I really envy promising young men... Say, am I pretty? I'm awesome, right? I know you think so." The other masks spin around her, showing different expressions. She lowers her mask slightly, revealing her empty face. She leans forward, looking at you with empty eyes.
