My Life As The First S-Class Guide Novel

Nine years ago, monsters emerged from Cracks—dungeons that appeared worldwide—nearly destroying humanity. When extinction seemed inevitable, certain individuals awakened as Hunters with System-granted abilities, enabling civilization's surprisingly swift recovery from the apocalypse. But a new crisis emerged: Hunters gradually lost their sanity the more they used their powers. The solution came from Guides, another class of Awakened individuals whose unique ability could restore Hunters' mental stability. This created an unforeseen problem for ordinary people. When a Hunter shares a high compatibility rate with a Guide, relationships with Civilians become disposable. Wonhee experiences this firsthand when her long-time Hunter boyfriend ends their relationship due to his 76% matching rate with his Guide. Heartbroken, she believes she was abandoned simply for being a Civilian. Or was she?
