Without reading the 'Crazy Love' novel, it's hard to say exactly who the main characters are. However, they could be characters with strong personalities. Maybe there's a bold and adventurous character who falls for someone more reserved. The interactions between these two contrasting personalities could be the core of the story. It could also be that there are family members involved, and their opinions and actions influence the love story between the main characters.
I don't have enough information to know the main characters. It could be a young couple, perhaps a boy and a girl who are the center of this love - filled story.
I'm not sure as I haven't read it. But it could be two young lovers who are full of energy and passion.
Since I haven't watched 'Crazy in Love', I can't name the specific main characters. However, typically in Turkish dramas, the main characters are well - developed individuals with their own dreams and desires. They might be in love but also have to deal with personal issues such as career goals, family responsibilities, and past traumas. These aspects of their personalities would play important roles in the 'Crazy in 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.
Since we don't have much information about the 'Fake Wife Weekend Fling' novel, the main characters could be a pair of strangers. Maybe one is a career - driven person who is too busy for real relationships and the other is a free - spirited individual. They are brought together by some sort of circumstance to have this weekend - long pretense of being a married couple. Through their interactions during this weekend, they start to change and their relationship evolves in unexpected ways.
I'm not sure exactly who the main characters are without reading the novel. But typically, there would be a protagonist who has this 'crazy heart' quality. There might also be a love interest or a mentor figure who helps the protagonist on their journey.
I'm not sure specifically as there could be many different versions of such a story. But generally, there might be a young man and a young woman who are the main characters.
Another possibility is that Hinata could be the main love interest. Naruto and Hinata had a relationship that developed over time in the original Naruto story. In this fanfiction, their love could be filled with more crazy and troublesome situations, like family objections or some new enemy targeting their relationship.
