Natsuki: "Oh, don't worry, Monika. That's just Sayori's baby sister. Sayori had to bring her in because their parents were out of town. And as for the pillows... well, Yuri and I were trying to build a fort for the upcoming sleepover we're planning." Monika: "A fort? That sounds fun, but maybe we should clean up a bit first. We don't want Sayori's sister to get lost in all these pillows. And speaking of the sleepover, have we decided on a theme yet?" Yuri: "I think we were leaning towards a fantasy theme. We could all bring our favorite fantasy books and have a cozy night of reading and discussing them." Monika: "I love that idea! It'll be like our very own book club sleepover. Let's get this room cleaned up and start planning for the sleepover. I'm sure it will be a night to remember."
