I received the notice that day. "We no longer need you. Please leave the station." It was the Chief's cold voice. Thinking back, my 'Encyclopedia' ability was bound to be replaced by a machine eventually. 'What am I supposed to do now?' The thought flashed through my mind as I packed my things and returned home.

I collapsed just like that. I began to resent my own ability. If only it had been something like teleportation. Haha. I've spent two days now talking, laughing, and chatting to myself in this pitch-black room where not a single ray of sunlight enters.

Gongryong fell into a deep depression, repeating cycles of self-loathing.

Encyclopedia. "..." The Encyclopedia said nothing. He called out again. Still, there was no answer. The only response was an endless silence. "Are you abandoning me too?" He clenched his fists. Anger surged through him like a violent wave. "Who do you think you are to leave me? Don't leave me. Where are you?" "Star of Criminology." Gongryong, who had entered the mental space of his own mind unable to control his emotions, fell silent. Was it because of the rows of fallen books lying before him? Gongryong looked up. It was just black. "Ah. I've already ruined everything. Me. It was all me. The job I worked so hard for. My only ability. And even myself. I was the cause. Why didn't I try to look at myself? Why... why..." Even though he hadn't been in contact for two days, no one had reached out to him. The problem was him. Why? Gongryong hugged a crumpled book right in front of him. "I'm sorry." The book in his arms slowly became damp from the water falling from above. Gongryong didn't even realize the book was being damaged by his own tears. His sobbing gradually quieted. There was no longer any emotion left in his eyes. Only negative feelings enveloped him. And this became the starting point of a life slowly burning away. He thought he should redefine these emotions—whether he was happy or sad. Gongryong soon defined the emptiness and resignation felt through self-loathing as 'happiness.' The wrong puzzle pieces were forced together. Self-loathing became a game for seeking fun. Anger became an overwhelming joy. Depression became a natural state. The twisted puzzle was finally complete, and a new library was formed. At the same time, an Encyclopedia that looked exactly like Gongryong returned. However, the Encyclopedia's expression was frozen and grim. Nevertheless, the Encyclopedia only watched its master. His master was already out of his mind. Without even thinking of leaving that space, he went mad within his own world.

Deokgae, Gongryong's junior and assistant, started to get worried as Gongryong hadn't answered his calls for eight days. Eventually, all the detectives of the Mystery Investigation Unit went to visit Gongryong's house in person.

Upon entering the house, the sight that greeted them was a living room where not a single ray of light entered due to blackout curtains, and furniture covered in a thin layer of dust.
