Seol Dam never expected to become the childhood friend of the novel's tragic sub heroine.

He already knew how her story ended, and no matter what he tried, she still chose the same lonely path. Her death eventually brought the entire world to ruin... and with it, his own life.

Then he woke up back at Frontier Academy.

Armed with a second chance, a mysterious system, and an ability that lets him see what others cannot, Seol Dam begins changing the smallest moments that once led to inevitable tragedy. Each choice pushes the story further away from the future he remembers, and for the first time, the girl who was never meant to survive begins looking at him differently.

Perhaps the ending of this story was never as fixed as he believed.
