Thriller: My Brother Is a Big Shot

【No romance + Not scary + Not brainless + Not overpowered + A little mystery + A little nurturing + Calm female lead】 Black patterns appear for no apparent reason, and the cursed are taken to another world. Those who return from that other world keep their mouths shut. Is it because they can’t speak, or because they won’t? The secrets hidden in the darkness will come to light one day. A young girl is chosen for no apparent reason and follows in their footsteps. In the so-called horror world of the “Box Realm,” she discovers traces of her brother’s existence. But as she ventures deeper, she gradually loses the ability to tell which of the two worlds is the one she truly belongs in. As the truth behind the games, the rules, and the System is revealed, and the secrets behind the council, the guilds, and the churches come to light, the truth of the whole world slowly emerges. The girl holds in her hands the keys to doors leading to different worlds. Which is the true reality: the eternal void or a brief, blazing existence? (Note: The System isn’t a cheat. It’s simply a tool given to everyone in the horror world.)
