Friendship is a very common theme. Since they are often paired in fanfiction, their relationship and how they support each other is a big part.
One common theme could be the exploration of their complex relationship. In a lot of fanfictions, they might start off as rivals and then develop a more intimate connection.
In female joey and seto lemon fanfiction, one common theme could be the journey of their relationship. It might start from a chance encounter or an initial dislike and then develop into a deeper connection. There could also be themes related to the world they exist in, if they are from a fictional world. For example, they might have to face some external threats together, which would strengthen their bond. Additionally, themes of love, both passionate and gentle, could be explored as their relationship progresses, along with the insecurities and jealousies that can come with new relationships.
Since I'm not well - versed in this specific fanfiction, it's hard to say for sure. But common themes in fanfictions in general could be friendship, adventure, or character development.
I'm not sure of the exact title, but there's a fanfiction that delves into the backstories of Joey and DJ Lemon. It shows how they grew up separately, with different musical influences, and then how their paths cross. It's really interesting as it explores their individual growth before they become friends and start making music together.
A common theme could be the exploration of their relationship dynamic. Given their different personalities in the original Yu - Gi - Oh! series (assuming they are from there), fanfics might focus on how they overcome their differences. For example, Seto's cold and calculating nature vs Joey's more hot - headed and impulsive one.
One common theme is also adventure. Fanfictions often take them on various adventures around New York or even further. It could be something as simple as exploring a new part of the city or getting involved in a wacky scheme that only they could come up with. Also, the theme of self - discovery is present. As they interact with each other, they learn more about themselves and grow as characters.
One major theme is career development. Given Joey's acting aspirations and Chandler's job in advertising. Fanfictions might show how they help each other in their respective careers. For example, there could be a story where Chandler uses his marketing skills to promote Joey's plays. Also, the theme of living together and their roommate life is often explored. Their apartment is like a character in itself in many fanfictions. There are stories about redecorating it or having crazy parties there. And of course, there are always the love and relationship themes, not just their own but also how they react to each other's love interests.
One common theme is family. Since family was a big part of the show, a lot of fanfiction focuses on expanding the family relationships.
One more theme that is often seen is second chances. In some fanfictions, Joey and Pacey have broken up and then get back together. This gives the writers a chance to explore how they've changed during the time apart and how they can make their relationship work better the second time around. There can also be themes related to career choices and how those impact their relationship.
Adventure is another common one. They often go on various adventures together, like exploring an old abandoned house or going on a hike in the mountains. This gives the writers a chance to show their teamwork and how they rely on one another. It also adds an element of excitement to the stories. In addition, some fanfictions also touch on the theme of growing up. They show how Charlie and Joey change and learn from their experiences as they get older.
