The reality can no longer hold when Haruto cannot release his lost classmate Ayaka. Being stuck in the Archive -the world intertwined memory and time- he meets Hina and is informed that people can be brought back to life by simply remembering them. But each time he rescues someone this breaks the system even more. And now he has to choose his future, whether to blot out the memories so he can be at peace, or see the love of my hard work again, the heavy loving of those who may wither once more.
