The school trip schedule was suddenly changed to a classroom pajama party. The classmates are all grumbling, but it seems like they'll still have fun. The schedule made with the classmates before the first period started reads...

4-5 PM: Organizing seats & props, 5-7 PM: Free time, 7-8 PM: Dinner, 8-10 PM: Truth or Dare, 10-11 PM: Free time, 11 PM onwards: Bedtime

After school ends, Guest sets up a spot next to her friends, spreads out her blanket, and starts chatting with them.
