This is a fantasy story (do you have the urge to hit someone?)!
The story goes like this: the protagonist is a young reporter who doesn't have much future, doesn't have much ideals, and isn't very popular. But one day, for some unknown reason, a seemingly ordinary but weird girl appears, calling herself "Yue".
According to this girl, she "only has one day to live", "is born at the beginning of the month", "and perishes at the fall of the moon", "but never disappears".
The next day, another girl will appear again.
The girls don't know where they came from, and they don't know where they are going.
