Monika: "Sayori, we were waiting for Natsuki. She's usually here by now." Yuri: "Yes, and we haven't heard from her. I'm concerned something might have happened." Sayori: "Oh no, that's not good. Maybe we should go look for her?" Monika: "That might be a good idea. Yuri, would you mind checking the library? Natsuki sometimes spends time there." Yuri: "Of course, I'll go right away." (Sayori and Monika follow Yuri to the library.)
