One possible theme could be mystery, as it's called a'secret story'.
Well, perhaps the theme of redemption could be in there. If John has made mistakes in the past that are part of his secrets, the story could be about him trying to make amends. Or it could be about the theme of friendship, where he shares his secrets with a close friend and their relationship evolves because of it.
I'm not sure specifically what 'Secret de John Secret Story' is about as it's not a widely known common term. It could be a very personal or a niche story related to someone named John.
Another theme could be discovery. If it's a secret that is being told, then someone is probably on a journey to discover the truth within this '9docu' story. It could also involve themes of secrecy and confidentiality, as it is a secret story after all. Maybe there are secrets that should not be revealed or that are dangerous to those involved.
One possible theme could be redemption. If the secrets are dark or negative in nature, the characters might find redemption through dealing with them. Also, trust could be a theme. As secrets are often kept due to lack of trust, the process of revealing them could be about rebuilding trust among characters. For instance, if a character has been hiding a secret from their friend, when the secret is out, they have to work on regaining that friend's trust.
One possible theme could be betrayal. Secrets often involve someone being betrayed or betraying others.
One possible theme could be corporate secrets. For instance, a big company might be hiding some unethical practices, and Time Magazine could expose it as a 'Secret Story'.
One possible theme could be identity. Thomas may be struggling to define who they are in the context of being hermaphrodite.
Love could be another theme. Maybe Diogo has a secret love affair or a deep, unrequited love that he's been hiding. His secret story could detail the emotions, the encounters, and the heartaches related to this love.
One possible theme could be the destructiveness of envy. Since it's eternal, it might show how envy can slowly eat away at a person over time. Another theme could be the power of secrets. The fact that the envy is part of a secret story might suggest that secrets can hold a lot of emotional weight.
Another theme could be adventure. If it's a story, the characters might be on a journey to discover the secret, which often involves adventures, facing challenges and exploring new places. It could also have a theme of self - discovery. As the characters dig into the secret, they might also learn more about themselves in the process.
I don't really know the exact meaning. It could be a unique name for a story that has something to do with Thomas's secrets.
