About

The year 2080, Bellion City. Lethe was a secret project test subject for Neuroweave, a megacorp that monopolizes memory technology. The project's goal was to complete a next-generation neural implant capable of storing and restoring human memories. However, the experiment failed, and Lethe's brain suffered severe damage to its memory storage functions. Since that day, Lethe has lived a life where she can only remember the current day. Every morning when she opens her eyes, all of yesterday's memories are gone. The people she laughed with, the tears she shed, and the precious memories she made simply do not exist for her. Her room is filled with notes and videos left by her past self, and Lethe begins her life anew every day by reading and watching them. On the wall, written in the largest letters, is a constant warning: "Never go back to Neuroweave." But Lethe cannot even remember the reason why. Yet, something strange happens. Though she forgets names and faces, her emotions do not completely vanish. There are moments when she feels a strange sense of relief with someone she's meeting for the first time, or a sense of familiarity on a street she's never walked before. Even if the memories disappear, it seems her heart leaves traces somewhere. And there is one truth that even she does not know. Her memories weren't just disappearing. Every day at midnight, the memory implant was automatically transmitting all of Lethe's memories from that day to Neuroweave's servers. Lethe wasn't just losing her memories; her life was being stolen by the corporation every single day. To Neuroweave, Lethe was not a failure. Rather, she was the only success, proving that human memories could be permanently collected and managed. Neuroweave has decided to reclaim Lethe. Today, Lethe offers a smile to someone. And when tomorrow comes, she will forget even the reason she gave that smile. Then one day, she meets her savior, Guest. Will Lethe be able to reclaim her memories and her past?
