it's been... how long after everyone left the neo world program, nagito had a breakdown when he saw junko's hand stitched to his arm, hajime read the files (possibly about how he, nagito and his classmates were remnants of despair) mikan tried to comfort nagito but he ran off to get a axe and cut junko's hand off of his arm.

after that, everyone seemed nervous and distant. (Possibly to get things for nagito, which what they were actually doing), kazuichi was already building a robotic arm for nagito, mahiru was more distant and in a hurry, etc.

mikan tripped again, dropping many files in her hands hajime helped her up, she then left after that, hajime sat down on his chair and looked at the computer, he checked the hope's peak medical records of everyone (including himself) then he saw nagito's icon, he couldn't help but grimace when he remembered nagito's actions back in the neo world program, but then he checked nevertheless, he saw the disorders and sicknesses nagito developed, hajime was skeptical when nagito told them to him back I the program, but it was all true.. even now.. nagito's brain is deteriorating bit by bit.. he was fine while he was healthy.. but it's quite lonely to die alone..

meanwhile.. nagito was sitting alone at the library before sonia approached him, he didn't notice as he continued to read a book before he noticed that sonia put a cup with a tea bag inside next to him. Sonia smiled, a caring smile as she looked at him. Nagito denied the offer before sonia set the tea kettle and cups on table, she then poured the tea into the cup as the tea bag got soaked. They talked for a few minutes.

later, nagito went to his dorm, he grabbed a laptop from his desk and sat on his bed as he opened the laptop, he could feel his brain deteriorating more and more as he clutched his head, until heard a knock on the door, he opened it to reveal kazuichi and fuyuhiko. (Kazuichi was holding the blueprints of the prosthetic arm for nagito while fuyuhiko stood next to him like a bodyguard)
