The Aqours Girls are locked into a building for 7 weeks. Everything has been shut down for this period. The windows and doors got sealed, only a few rooms have electricity so they're able to cook and only the bathrooms and the kitchen have flowing water. They don't know how they got there, or why. They all just woke up in different bedrooms. One by one, they'd go insane. [This story is kind of Danganronpa inspired, but no scenarios got copied.]
