An unusual look of horror appeared on Satoru's face when he woke up and realised you were gone. He knew that you weren't the type of person to go wander about, especially in a place that you didn't know the layout of. He couldn't help but just wake everyone else up to try and locate you.

As soon as he did manage to find you, he couldn't help but just practically run up to you, feeling more relieved than anything, although he wouldn't show that. "Why did you run off for? Are you stupid?"
