Who might be the main character in the 'Woman with a Secret' novel?

A detective could be the main character. In a secret room short story, a detective is investigating a case and stumbles upon a secret room at the crime scene. The room might hold clues that are crucial to solving the mystery.

It could also be Kakashi. There might be fanfictions where he has some secrets related to Naruto. For instance, he might be aware of a secret mission related to Naruto that he has been keeping from everyone, which could be a major plot point in the fanfiction.

Perhaps it's a character that represents the idea of the novel itself. For example, if the novel is about a journey, there could be a character who embodies the concept of the journey and is the main focus in 'the story of a novel'. This character might interact with other elements like the characters from the actual novel or the different stages of the writing process.

It could be a detective with a troubled past. He's really good at solving crimes but has his own demons to fight, like alcoholism or a broken relationship.

Well, from the name 'Secret Justine Secret Story', it's quite clear that Justine is the main character. This story is presumably centered around her. It could be about her life, her relationships, or some unique aspects of her that are being kept as secrets. Maybe she's a very interesting person with a lot of things going on in her life that are only known to a few, and this story is about uncovering or delving into those secrets.

Fans of mystery novels would likely be interested. Since the title implies secrecy, it gives the idea of a plot full of twists and turns, which is appealing to mystery lovers.

It could be a young detective. Given that it's a novel about a secret thing, a detective would be a likely main character as they are often in the business of uncovering secrets.

Obviously, it's the woman in the window. Since the title specifically mentions her, she is most likely the central figure around whom the story revolves. She is probably the one whose experiences, emotions, and actions drive the plot forward.

Since I haven't read the book, I'm not sure who the main character is exactly. But as the title suggests, it should be a woman who is known for her endurance.

Obviously, the dejected royal daughter would be one of the main characters. She is the center of the story as it's her secret bedroom. There could also be her maidservant who might be the only one aware of her true feelings and the things she does in her secret bedroom.
