The main character could be someone who has had a life - changing experience that will be 'forever in my heart', and the other characters help shape that experience.
It might also be about a family. Family relationships can be very strong and some memories or family members can be 'forever in my heart'. So the main characters could be different family members and the story could revolve around their relationships and shared experiences.
I'm not sure as the name doesn't give a direct hint about the main characters. It could be about any set of characters from a particular fandom that the author of the fanfic has chosen to focus on while highlighting their child - like qualities.
I'm not sure as I haven't read the novel specifically. But usually, there would be a male and a female lead whose relationship is the focus of the story.
It could be about loss and remembrance. The title gives the impression that there is something or someone that is held dear in the heart forever, perhaps because they are no longer present. So it might explore how a character copes with that loss and keeps the memories alive.

Since I don't have the 'hear my heart novel' at hand, it's difficult to say exactly who the main characters are. However, in most novels, the main characters are those who drive the plot forward. They could be characters with a strong goal or desire. For example, in a coming - of - age story, it might be a teenager trying to find their place in the world. In a mystery novel, it could be the detective or the person who has a connection to the mystery. In the 'hear my heart novel', it could be a character who has a heart - related theme, perhaps someone who has a special ability to understand others' emotions deeply or someone who is on a journey to heal their own broken heart.

There might be a love interest. If the theme is related to love and heartbreak, there would be a character with whom the main character has a romantic relationship that causes the 'burning heart' situation.
