Dreambreaker : The extra from 2393

Summary:

“Reality is stranger than fiction”—There is this saying, I don’t know who said it, but it certainly holds true for a certain unlucky man.
In a futuristic apocalyptic world, where Earth is ravaged by natural disasters and cataclysms, it feels like the world is on the brink of doom.
However, amidst the chaos, humanity still persists.
Yet, everything seems to be spiraling downhill.
In this apocalypse-ridden world, Noah, who is suffering from a rare blood disease, wonders if he will ever survive.
Fortunately, his grandfather-a brilliant scientist, discovers the cure! Nano machines!
Finally, Noah can reclaim a normal life… but alas, fate has other plans in store for him.
After one unfortunate cataclysmic event, when Noah opens his eyes, he finds himself in an entirely different world—only to realize that he has fallen inside the very novel he wrote as a kid.
