I've read so many NCT fanfics focusing on Jeno, and his emotional vulnerability is often the heart of the slow-burn romance. Writers love to explore his quiet strength masking deeper insecurities, which makes the payoff of him finally opening up to his
love interest incredibly satisfying. The tension builds because Jeno isn't the type to wear his heart on his sleeve—his vulnerability comes through small gestures, like lingering touches or hesitant confessions.
What makes it work is how authors contrast his usual composed demeanor with moments of raw emotion. In one fic, he's the dependable leader until he breaks down after a failed mission, and his love interest sees him cry for the first time. That moment changes everything. The slow burn thrives on these cracks in his armor, making the eventual romance feel earned rather than rushed. Jeno's vulnerability isn't weakness; it's the key to his character's depth, and that's why fans keep coming back for more.
