In the shadows of the S Ranked Main character

Kai was a 17-year-old dropout. A NEET. A background character in real life with nothing to his name but bitterness, novels, and guilt. After his parents died, he gave up on the world. People were fake. Dreams were pointless. And that one novel he kept reading? He hated it especially the main character, June. Perfect, noble, always standing tall. Everything Kai wasn’t. Then, one night, a voice asked: “What if you did meet June?” He said yes, half-asleep and half-mocking. Now he’s trapped in the novel. Isikeid. But he’s not June. He’s not a hero. He’s not even in the main cast. He’s an extra in the background of a world he knows too well and he’s had enough of watching things play out the same way. This time, he’s going to change everything. Whether the world likes it or not.
