The story takes place in a completely closed women's college called Qingwu Women's College.
School regulations:
• Once the school gate is closed, you are not allowed to go out for half a year;
• The power in the dormitory will be cut off at 10 p. M., And leaving the room is prohibited;
• The dormitory building is not available for rent or open to the public.
However, no one has ever actually seen "off campus." No one really leaves school.
What's even more bizarre is that the "occupancy number" of each dormitory in the dormitory building is always "the number that no one doubts in the end."
