When the main character for a story is rather dull and doesn´t talk much/ doesn´t reveal much its true self to the other characters I wonder about how I should develop it. The character has feelings of course and they´re actually deep unlike the impression it can give towards the other characters from the story and the reader, but for the sake of the story I need to make the reader like my character and feel intrigued by its past/dreams/motivations. My question is the following: I do really want this character to be you know, one of those "closed characters" but the reader needs to keep interested and know about the character as the story goes by. Therefore, I am planning this: The first developments from this character will happen inside the character´s own mind, so the reader can get more "intimate" to the character, while the other characters will still know nothing. Do you have good advice on how to do this in a subtle way? Another detail: This character will trust other characters and when that happens、will reveal the way he is to them. However that happens later because I want to give this "mystery aura" to the main character.
