(Not unlimited flow, no CP, no ambiguity. The heroine is not weak, white and thin, not brainless, nor is she particularly sunny and cheerful. She has an arrogant personality and is a little bit arrogant. There will be a plot of the protagonist in school)
This is the seventh floor, where it all begins.
Chang Du is just an ordinary high school sophomore who likes to violate minor rules and make minor mistakes. I don't know if it's because of luck or because she's obedient, but the frequency of her notifications has been dropping rapidly. But before she could be happy, a mysterious organization came to find her.
Her destiny went off track, and she entered a different world, where warmth and death were constant companions. She struggled in the whirlpool, trying to find a way to survive, even if the hope was slim.
Trying his best to seize the chance to live, Chang Du stared at the boundless "emptiness" with wounds all over his body...
It was then that she realized that as a speck of dust, all her efforts seemed so... Ridiculous.
Intention: Even if you die, there is still hope of life
