I Transmigrated Into a Spy War and Became a Secretary Who Knows Everything

After a thirteen-time binge-watch, Hong Ji-woo awakens as the expendable \"Secretary Hong\" in his favorite spy thriller. Trapped in the tumultuous Jinhai City of 1948, surrounded by cunning agents, ruthless warlords, and shifting loyalties, his initial goal is simple: survive this deadly game where he’s just an extra. But Hong Ji-woo has a cheat code: he's seen the entire series. Every character's hidden agenda, every plot twist, every historical event is etched in his mind. This isn't a story to watch; it's a meticulously detailed blueprint of the future. He leverages this unparalleled knowledge to outmaneuver rivals, collect hidden fortunes, and charm influential figures, all while pretending to be a mere bystander. He just wants to \"eat melons\" from the sidelines, profiting from the chaos without getting his hands dirty. Yet, as his subtle manipulations begin to drastically alter the original timeline, he realizes his seemingly safe vantage point is pulling him deeper into the spy war’s core, where the ultimate prize—or ultimate trap—awaits.
