Ah Qiu is the [protagonist] of the horror world. This world is a normal [white world] at the beginning and middle of each month, and a [night world] full of all kinds of things at the end of the month.
As the protagonist, she will be transported to a place at night at the end of the month, and she can only go back after clearing that place.
As the protagonist, she must clear the level 100 times before she has a chance to escape from this reincarnation.
She has passed the level many times, but each time the difficulty increases and she becomes more and more strenuous. Fortunately, she is not alone. The other world will then select [teammates] and come to this world to help her.
But one day, all her teammates appeared in front of her, looking at each other. She was horrified to discover that her teammates were not only in the same world, but they all knew each other.
"This is what I said before, the girl who will live and die together..."
"Didn't she make an agreement with me that if she could escape from this hellish place, she would watch a fireworks show with me?"
"Aqiu, didn't you promise to be with me?"
Aqiu:? ? ? Did I say that? And it turns out you all know each other!
