what is climax in the story

Yoo Jihwan was just an ordinary reader. He never dreamed of adventure, never sought glory. He was simply a boy who found comfort in books—a world where struggles had meaning, where endings were earned, and where every action carried weight. But when he finishes the final chapter of a novel, something impossible happens. A message appears before his eyes: [The world has gained a new Reader.] And in the next moment, he is sucked into the story itself. Thrown into a mysterious game where books are no longer fiction but real, deadly worlds, Jihwan must survive challenges designed by unseen hands. Each book holds trials, monsters, and secrets, and failure means an endless loop of suffering. But the deeper he goes, the more he realizes— He was never meant to escape. For there is a Wall that divides the Beginning and the Climax. And beyond that Wall exists a being trapped in eternal stillness: The Reader of the Climax. And Jihwan was always meant to take his place. As he struggles against fate, forms fragile bonds, and uncovers the truth of the game, one question remains— Can he break the cycle, or was he destined to be forgotten from the very beginning?
