Seo Won was nothing special. His life was ordinary, boring... until he found [The 9 Abysses of Ruin], a novel he quickly became obsessed with. The story followed Jinwoo Kim, a hero trapped in an endless cycle of trying to save nine maidens, only to fail over and over again. But Seo Won didn’t care about the maidens, what captivated him was Jinwoo, his relentless fight, his quiet despair, and the way he kept going, no matter how much he lost. Then the story ended. And it ended cruelly. Jinwoo failed for the last time, swallowed by the abyss after more than a thousand attempts. Seo Won was devastated. Furious. He cursed the author, the story, and even Jinwoo for not finding a way to win. But nothing could change the ending. Or so he thought. The next thing Seo Won knew, he woke up inside the novel. But he wasn’t Jinwoo. He wasn’t even important. He was just some random extra, a pretty-faced student with blonde hair, green eyes, and a delicate, almost angelic appearance. None of it mattered, though. Seo Won had one goal: to save Jinwoo Kim, no matter what. There was just one problem. The nine maidens, the ones Jinwoo had spent lifetimes trying to save, weren’t interested in him anymore. They all had their eyes on Seo Won. The Tsundere Princess: "Ugh, who does he think he is? I’m obviously the better choice." The Shy Daughter of the Headmistress: "You’ll stay with me forever, won’t you? You have to." The Ice Tyrant: "My heart has been frozen for so long… you’re the only one who can melt it." The Novice Nun: "My sweet little angel… I’ll protect you. I promise." The Mischievous Twins: "Ehehe~ big brother, don’t look away from us. We’re just getting started." The Psychopathic Genius: "You’re so adorable. I wonder… how much can you endure?" The Kind Teacher: "Stay after class. There’s something special I want to show you." Jinwoo’s Little Sister: "Don’t you dare take my brother away! He’s mine." The fox girl: "I’ve been lost for so long… but you make me feel alive again. Why?" Meanwhile, Jinwoo, the protagonist Seo Won desperately wanted to save, looked at him with a obsessed smile and said: "I fell into the abyss, but you saved me... now it’s my turn."
