I don't know the specific main characters as I haven't read the novel. You might need to check the book itself or look for reviews that mention the main characters.
There is no way to accurately determine the main characters just from the title. But let's make some speculations. It could be a story about a young person, perhaps a girl or a boy, who has faced a great deal of loss or hardship and feels they have nothing tangible to offer in life. There might be a mentor - like figure who helps the protagonist understand the value of their heart. And there could also be a group of friends or family members who play important roles in the character's journey of realizing what it means to give their heart, whether in relationships, in achieving dreams, or in facing difficulties.
Since I haven't read the novel, it's hard to say for sure. However, based on the title, it could be a story about an individual who is the central character. This person might be in a difficult situation where they feel they have no resources to offer but their heart. There could also be other characters around this protagonist who either support or oppose them, perhaps a love interest who is the recipient of this 'heart - giving', or antagonists who try to take advantage of the protagonist's vulnerability.
I'm not sure as I haven't read it specifically. But generally, it could be about self - sacrifice or the depth of emotions, given the title mentions having only one's heart to give.
Since the title implies that there is 'nothing to give but my heart', it could also be about the value of intangible things like emotions and love in a world that often focuses on material possessions. The novel might be showing how a person's heart, their love, and their emotional self can be the most important and powerful thing they can offer, whether it's in a relationship, a family, or a struggle against difficult circumstances.
You can try some popular e - book platforms like Amazon Kindle or Google Play Books. They often have a wide range of online novels available.
I'm not sure as I haven't read the specific 'unbreak my heart novel'. But usually in this kind of novel, there would be a protagonist who is likely to be the one with the broken heart.
I don't know the specific main characters in this novel as I haven't read it. Maybe there's a young protagonist, male or female, who is on a journey of some sort.
Perhaps it's a story about a single character and their journey, with the people they meet along the way being important secondary characters. 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.
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.
Since I haven't read the novel, I can't say for sure. But it could be a couple, like a man and a woman where one of them is the 'heart - player'.
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.
Maybe there is a strong - willed female lead. She could be the one who has to steel her heart in a male - dominated world. For example, she might be facing discrimination or hardships in her career or personal life, and she has to toughen up. There could also be a mentor - like character who helps her along the way.
