Often in such a fanfic, the main character, the bodyguard, might have a partner or sidekick. This character could be aware of some of the lies and help the bodyguard keep up the facade. And there could be a love interest for the bodyguard, which adds another layer of complexity to the story as the bodyguard has to lie to this person too in order to protect them.
Typically, the bodyguard is one of the main characters. He is the one who is tasked with protecting someone.
Well, it could be about a lot of things.

Maybe it's set in a fantasy world where the bodyguard has magical abilities but uses lies to outwit enemies.
It could be a new character introduced specifically for the fanfiction. This character could be someone who stumbles upon the world of lies and bodyguards by accident, like a curious journalist or a lost traveler. Their naivete or outsider perspective could drive the story forward as they try to make sense of it all.
