No, he was just a bad boy, maybe he would have been a writer or a painter in the future. On the night the plane parts fell in his room, he was awakened by a voice that said the world would end in 28 days, 6 hours, 42 minutes and 12 seconds. He believes the world will end, but what does this have to do with him?
Later, he saw Rabbit Man, who was instigated to vent violence; he saw cylindrical water waves on everyone's chest, just like time travel written in the book; he met a girl who appeared like a pre-apocalyptic girl bright light.
Is all of this a predestined alternative reality, or an illusion haunted by death?
I think when he dialed back the time for that girl, he probably didn't realize that the world was changed by him too.
Under the rendering of the sad Mad World, the world was rescued and the story ended, but the psychological sadness did not disappear.
