Since I'm not familiar with 'Trouble Boy Love Story', I can only make assumptions about the main characters. The titular trouble boy would be a key character for sure. There might be a love interest, could be another young person, maybe a friend or a stranger who comes into his life and changes his perspective. There could also be side characters like his family members or friends who either contribute to his 'trouble' or help him in his journey of love.
As I haven't had the chance to read 'Trouble Boy Love Story', it's difficult to say who the main characters are. But it's likely to have the trouble boy as one of the main characters, and perhaps the person he falls in love with, like a girl who might be his opposite in some ways, for example, very calm and stable while he is all in chaos.
The 'Trouble Boy Hitmaker' and the 'Trouble Love Story' could be intertwined in many ways. The hitmaker could be using their music as a form of therapy to deal with their own love - related problems. Their lyrics might tell the story of their troubled love life, and this authenticity could be what makes their songs so popular. For instance, their music could be about a love that was lost due to jealousy or a lack of communication, and fans are drawn to the rawness of these emotions.
I'm not sure specifically as the name doesn't give away the characters directly. But typically in a love novel, there would be the two lovers at the center. Maybe a male and a female character who are from different backgrounds or have different personalities.
The connection could be that the Trouble Boy Hitmaker draws inspiration from his own Trouble Love Story to create music. His personal experiences in love, which are full of trouble, might be the source material for his hit songs.
It's possible that there is a lone detective - like character. This person is drawn to the mystery and trouble that is scaring people. They are brave and determined to solve the mystery behind the scary events, and in the process, they become the main focus of the story as they face the various horrors.
As there is not much information given, it's difficult to say exactly who the main characters are. But surely there is the boy, and probably a girl or another boy that he falls in love with. There might also be some side characters like friends or family members who play important roles in the story, for example, friends who encourage the boy in his love pursuit or family members who either support or oppose the relationship.
As we don't have much information about this 'jamesy boy love story', the main character is surely Jamesy. And probably there is a love interest, perhaps a girl, but we don't know her name yet.
I don't have enough information to determine who the main characters are in this 'blind boy love story'.
Most likely Ben would be one of the main characters. Since it's a Ben 10 fanfiction, he's usually at the center of things. And if it's about love, perhaps his love interest, whoever that may be in this story, would also be a main character. Maybe Gwen could also play an important role, either as a friend giving advice or getting involved in some way in the love - related drama.
I'm not sure specifically as the title doesn't give clear indication of the characters. It could be original characters created by the fanfic author. Maybe it's a story about a young couple who are the main focus of the 'trouble with love' part.
Gray could also be a part of it. He might be the one teasing Natsu about his love problems or even getting involved in some sort of love triangle situation with Natsu. And Erza, she could be the voice of reason, trying to get Natsu to sort out his feelings in a more proper way, while also dealing with her own reactions to Natsu's love - crazed antics.
