"If you tell the truth, you don't have to remember anything. Right now I'm having amnesia and déjà vu at the same time. I think I've forgotten this before. They say our memory is a more perfect world than the universe: it gives back life to those who no longer exist." (Y/N) Sumiko, a young, diligent 14-year-old, is pushed into the fray after being released from the hospital following a horrible disaster. She is now left cursed with slight amnesia, and all she has left is the memory of the occurrence, which is permanently imprinted into her brain. Can she overcome this? It is heavily doubted. Until, she comes face to face with a letter, which delivers awful news about what her future might be if she trusts the wrong people. With this, (Y/N) offers her support to prevent such tragic fortunes out of fear and perplexity. But little does she realize that this will only result in catastrophe for... The girl behind the counter.
