   Summary

   ...I must have dozed off, because I suddenly became alert when I heard a phone. Her phone. It was ringing. Instantly she pulled it out to look at it. I turned my head back up to look at her face. My eyes widened once I saw what happened next.
   Shimamura, why were you making that face...? That's not a face you should make when your boss contacts you. Why are you so happy...? Why do you look so excited? Don't look at someone else like that. Don't care about anyone else so much that you'd make a different expression.
   "Ah, um... Adachi. I think I'm gonna... head home for today, okay? I'll see you some other time."
   Her voice was breathier than usual. The eagerness in her voice was so different than she usually sounded.
   Stop it, my heart. Please don't hurt like this.
