One of the best moments could be when Joey takes the reader to one of his acting gigs. It gives the reader a chance to see his passion up close. Another great moment might be when they have a picnic in Central Park and Joey tells his hilarious stories, making the reader laugh uncontrollably. Also, the moment when Joey tries to cook for the reader but messes it up in a really cute way is also a memorable one in many fanfictions.
One popular trope is the 'fake dating' scenario. Joey might need a date for an event and asks the reader to pretend to be his girlfriend. This often leads to real feelings developing. Another is the 'roommate' trope, where they live together and slowly fall for each other. There's also the 'teaching Joey something new' trope, like the reader teaching him a new language or a new hobby, which creates a bond between them.
Yes, there are quite a few. You can find some on popular fanfiction websites. Just search for 'Joey Tribbiani and Rachel Green love' and you'll likely come across some interesting stories.
You can try websites like FanFiction.net or Archive of Our Own (AO3). They have a large collection of fanfictions, and you should be able to find some dedicated to Joey and Rachel's relationship.
A friendship moment could be when Rachel is having a bad day at work and Joey just shows up with a pizza and some goofy jokes to cheer her up. They sit on the couch, eat pizza, and Joey tells her all about his latest audition disasters, which makes Rachel laugh and forget about her own problems.
They could also be involved in a neighborhood event. Maybe they are both trying to raise money for a local cause. Joey could use his charm to attract donors, while Rachel uses her organizational skills. Along the way, they face challenges like not getting enough publicity for the event, but they work together to solve it and strengthen their friendship.
One popular plotline is the rivalry intensifying. Joey is always looking to prove he can beat Kaiba at his own game, so there are often duels where the stakes are high and the tension is palpable. Another plotline could be an unexpected alliance. Maybe there's a new and powerful enemy in the dueling world, and they have to put aside their differences to defeat it. And sometimes, there are fanfictions where Joey discovers a softer side to Kaiba, which changes their dynamic in an interesting way.
In Kaiba x Joey possessive fanfiction, the characters' personalities are usually exaggerated. Kaiba, with his pride and power, might use his resources to keep Joey close. Joey, on the other hand, may struggle with this possessiveness while also having his own feelings for Kaiba. It makes for an interesting dynamic.
Friendship is a very common theme. Most of these fanfictions start with their existing friendship and then build on it. Another theme is self - discovery. As they interact more closely, they often learn more about themselves.
