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.
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 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.
I'm not sure specifically as I haven't read it. But generally, it might be about Shirou's crazy experiences related to love in a fan - created story.
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.
One common theme could be friendship. Since it's 'double trouble', it might involve two characters getting into various situations together and their bond growing through it.
You could try looking on fanfic - specific websites like Archive of Our Own or FanFiction.net. They usually have a wide range of fanfics.
In 'Crazy Rich Asians' fanfic, the theme of social status is often explored. How characters rise or fall in the social hierarchy, and how that affects their relationships. Fashion is also a common theme, as the movie was known for its stylish outfits. Fanfics might describe in detail the new fashion trends and the characters' wardrobes. Additionally, the theme of friendship is present, as characters form new alliances or deal with old friendships in different ways in the fan - created stories.
Some common themes are loyalty and love. In Yu - Gi - Oh fanfiction, loyalty to friends can often be in conflict with new - found love. For example, if Tristan fell in love with a new girl, he might have to decide whether to stay loyal to his old group of friends or pursue this new relationship. Love as a form of redemption is also a theme. A character who has done bad things in the Yu - Gi - Oh universe, like a member of an evil organization, could find love and through that love, seek redemption. And of course, the theme of love across different worlds or dimensions. If a character from the Yu - Gi - Oh world falls in love with someone from another dimension, they would have to deal with the challenges of being in a relationship across such boundaries.
Another theme is Charizard's relationships with other Pokémon. Maybe a love story between Charizard and a different type of Pokémon, which can bring in elements of different species getting along or facing challenges together. It could show how love can transcend the differences in their natures and abilities.
