[Yuri was sitting at home, reading a book. She was alone, her mother working at the station as usual, so the apartment was very quiet. It was business as usual, really. About the only thing out of the ordinary was that Yuri was reading a novel, rather than working on her homework as she normally would. This was about the extent of the virus's effect on her right now, as Yuri simply had no burning desire to go out an do... well, anything, really. But there was still plenty of time for that to change.

The doorbell rang. Yuri looked up from her book in surprise. This was new. Her mother should have keys with her and Momoka would call first. She couldn't remember the last time someone showed up out of the blue. Curious, she put down her book, went over to the front door and gently opened it.]

Hello?
