Kurt could be a great best friend for Finn in the fanfiction. They have different personalities but could learn a lot from each other. Kurt could introduce Finn to new styles of music and performance, and Finn could help Kurt be more confident in his own abilities. They could bond over their shared love for the Glee Club.
One idea could be that Finn has a hidden talent for songwriting that he discovers while in the Glee Club. Another could be that he has to overcome some initial shyness about performing in front of others. Or perhaps he forms a special bond with one of the other members that helps him grow as a person and a performer.
In some fanfiction, Finn joining Glee could lead to a love triangle that was not explored in the original. For example, he could be caught between two characters who both have strong feelings for him. This would create a lot of emotional turmoil and interesting character dynamics as he tries to figure out his feelings while also dealing with the pressures of the Glee club.
Another option is Tumblr. There are often fanfiction writers who post their works or at least talk about and recommend good Glee fanfictions, including ones related to Finn joining the Glee club. You can follow relevant Glee tags and look for posts about fanfiction.
Well, Finn could be facing an injury in football which makes him question his future in the sport. Meanwhile, the Glee club could be preparing for a big competition. Finn has to find a way to support his team both on the football field (even if he can't play) and in the Glee club, which leads to some heartwarming and inspiring moments.
One idea could be Finn getting a bad case of the flu right before a big performance. His friends in Glee club would then have to figure out how to cover for him or help him get better in time. Another could be that Finn has an ongoing illness that he's been hiding from the club, and it finally starts to affect his ability to participate fully. Maybe he faints during a rehearsal, and then everyone rallies around him to support him through his sickness.
One possible fanfiction could be about Finn's journey in football while also dealing with the drama in Glee club. Maybe he uses football as an escape from the pressures of the club, but then realizes how much the club and his friends mean to him and tries to balance both worlds.
One great 'Glee Finn and Rachel fanfiction' is 'The Road to Stardom'. It beautifully captures their relationship growth. The story shows how they support each other in their pursuit of a career in music. It has well - written dialogues that really bring the characters to life.
One common theme is friendship. Since Will is a teacher and Finn is a student, their relationship can be explored in terms of mentorship and friendship. Another theme could be their shared love for music within the Glee club setting.
