I Reincarnated as The Protagonist's Best Friend

After a long, exhausting life as an overworked office worker, he suddenly finds himself reborn inside the very novel he was reading.

Unfortunately, he isn’t the hero.

He’s the hero’s best friend—a supporting character whose only real purpose in the original story is to die.

And not even much later. His death is practically guaranteed.

But this time, things are going to be different.

Armed with knowledge of the story and determined not to become a tragic footnote, he decides to take control of his own fate. Instead of following the script, he’ll carve out a new path—one where he actually gets to live.

Of course, changing the story won’t be easy. Every choice could alter the future in unexpected ways, and staying alive might be harder than he thought.

Still, he’s had enough of living for other people.

In this new life, he plans to survive, rewrite his destiny, and maybe even become more than just the hero’s sidekick.
