In a fanfic, the crazy trouble with love could be unrequited love. One character might be deeply in love with another who doesn't feel the same way, leading to all sorts of heartache and drama. For example, they might constantly try to win the other's affection, but only face rejection and disappointment.
Communication is key. If the characters sit down and talk honestly about their feelings, misunderstandings can be cleared up. For instance, if it was a case of misinterpreting a friendly gesture as romantic, a simple conversation can set things right.
Well, it could be that Peter falls in love with someone he shouldn't, like a villain's daughter perhaps. This would lead to all sorts of crazy trouble as his friends and the city he protects might not accept it.
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.
Well, it could be about all kinds of crazy things that happen when love is involved in the Ben 10 universe. Maybe it's about a character falling in love with an alien they meet during their adventures. Or perhaps it's about the troubles that come with having a relationship while also being a hero and having to deal with all the alien threats.
Perhaps Peter realizes that his superhero responsibilities are more important at the moment and decides to put his love life on hold. By focusing on being a hero, he might find that the 'crazy trouble with love' slowly fades away as he has less time to get into relationship 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.
In this kind of fanfic, a likely theme is the struggle between heart and mind. The characters may have strong emotions for someone but their rational side tells them it might not be a good idea. Additionally, the theme of growth through love can be present. Through the experiences in their love - related troubles, the characters may grow and develop as individuals.
One common theme is miscommunication. Ash often misunderstands the feelings of others or vice versa, which leads to all sorts of trouble in the love department.
