I Couldn't Care Less About This World's Ending

In the original novel, he was the embodiment of incompetence and the root cause of the story’s disastrous ending. Now, he’s been reincarnated as Kafka Sonder, a troublesome character who was cut from the webtoon adaptation altogether. In his previous life, he read the adaptation, so he could try to change his fate... But he lacks the energy, lacks the motivation, and simply doesn’t care if the world ends or not. So he chooses to do nothing—to live quietly, like a mouse, hoping to pass unnoticed. Even when the story starts veering off-script. Even when he keeps running into Soren, the protagonist he wanted to avoid more than anything. He's determined to never get involved. He shouldn’t forget that… But the moment he dares to wish for a happy ending—disaster strikes. Now, in the chaos he brought upon himself, what kind of ending awaits this world?
