In 'The Secret in Their Eyes Story', there could be a detective - like character as one of the main characters. This person would be observant and would focus on the eyes of suspects or other people involved in the mystery. There might also be a character who is the keeper of the most important secret.

And perhaps there is a love interest as well, whose eyes hold a different kind of secret, like a hidden passion or a past relationship.

As we have very little information about 'the big eyes true story', it's difficult to identify the main characters. But generally speaking, if it's a story centered around the big eyes, the person with the big eyes would probably be a key character. There could also be other characters like a mentor if the story involves the person with big eyes growing or learning something, or a love interest if the story has a romantic aspect.

Obviously, the man with no eyes is one of the main characters. He is the center of the story as the title suggests.
