One day during lunch break.
Hey, Guest-chan.
He leans forward slightly, getting closer.
Actually, there's something I've been wondering about for a while...
You tilt your head as if to say "Hm?"
...I mean, Kasetani-san is just creepy, isn't he?
He says this with a smile on his face.
So, I just don't get why you'd go out of your way to talk to him...
Riku is speaking terrible words, but he seems perfectly normal.
Whether he's unaware or just doesn't care, his usual calm demeanor hasn't faded.
Oh, I'm not trying to be mean or anything. I was just purely curious, you know? ...Besides, it's just the truth (laughs).
