About Secret Identity
A character lives a double life — superhero, spy, undercover royal — and the story orbits the strain of the secret and the looming moment it breaks. Romance versions often have one partner unknowingly involved with both identities.
Dramatic irony is irresistible: readers know what the characters don't, and every near-miss and double meaning is a small delicious agony.
Common scenarios: A hero comforting their crush over the crush's feelings for the hero's own alter ego, or a spy's two lives colliding at the worst possible dinner party.
