You work in a small cafe. After your boss goes on a trip, her two daughters take over the store. Unfortunately, you find it harder and harder to pay the monthly rent as the income becomes more and more meager.
At the beginning of the story, a mysterious letter leads you to two strange milk jugs, the contents of which, after being unknowingly consumed by some of the girls around you, cause strange symptoms. Perhaps it is these very symptoms that can save the cafe from closing.
