I think Artie should be in the fanfiction. He could be the one filming their wedding and making a special video for them. Tina could also be there. She might be a bit jealous at first but then realizes how perfect Puck and Rachel are for each other. And Brittany. She could do some really cute and unexpected things at the wedding, like dancing with a bouquet of flowers instead of throwing it.
Quinn would be an important character to include. Given her past relationship with Puck, her presence at the wedding could add some drama and tension. Santana could also be part of it. She could be the sassy friend who makes sarcastic comments about the wedding but deep down is happy for them. And of course, Mr. Schue. He could give a heartfelt speech at their wedding about how far they've come.
Definitely Toad. Toad has been a loyal friend to both Mario and Peach. He could be the one helping with all the little details of the wedding, like arranging the flowers or setting up the chairs. Yoshi could also be a great addition. He could carry Mario and Peach on their honeymoon as a fun way of transportation. Luigi should be there too, as Mario's brother, he would be an important part of the celebration.
Puck would probably start to show his softer side. Normally he's tough and a bit rough around the edges, but a baby would make him more empathetic. He'd learn to communicate better, especially with Rachel, as they navigate this new phase of their lives. Rachel would become more nurturing. She has a big heart already, but having a baby would intensify that. She would also become more assertive in making sure Puck is fully involved in the baby's life. She doesn't want to be a single mother, so she'll push Puck to step up and be a good dad. And they would both learn to sacrifice some of their own wants for the sake of their new family.
One idea could be that they decide to get married suddenly after realizing their deep love during a trip. They face opposition from their friends at first, thinking it's too rushed. But Puck and Rachel are determined. They plan a simple yet beautiful wedding with just their closest family and friends. In the end, everyone sees how happy they are together and supports their marriage.
Obviously, Brock should be included. He has been Ash's friend for a long time and could be Ash's best man. He would also add some comical moments to the story, like when he flirts with the female guests at the wedding. Max, May's little brother, would also be a great addition. He could be a bit of a troublemaker at first, not fully understanding why his sister is getting married, but then come around and be really happy for her. And of course, all of Ash's Pokémon, like Pikachu, should be there. Pikachu could even be the ring - bearer in a really cute way.
Santana could be a great addition. She could be Rachel's best friend who gives her brutally honest advice about married life. Like when Rachel has a fight with Jesse, Santana would be there to say something like 'Girl, you need to put your foot down or he'll walk all over you.'
There isn't really a definitive list of the best authors for this fanfiction. However, you can look for authors who have been writing in the puck and rachel lemon fandom for a long time. These authors usually have a better understanding of the characters and their dynamics. Also, those who are actively engaged with the readers, answering comments and taking suggestions, often produce great works. You might have to explore different platforms and read a few samples to find the authors whose writing style you like.
Archive of Our Own (AO3) is another great place. It has a well - organized tagging system. So, you can search for 'Puck' and 'Rachel' and then filter by the 'Married' tag to find the stories you're interested in.
There's 'Our Married Bliss' which focuses on their musical journey together as a married couple. It beautifully portrays how their shared passion for music strengthens their bond. Puck and Rachel are shown supporting each other in auditions and musical projects.
I think Quinn could be a great addition. She could be the one who initially misunderstands the situation between Sam and Rachel and causes some drama. Also, Finn could be included as he might have his own feelings about Rachel being with Sam.
For Puck, he might start to take life more seriously. Usually a bit of a bad boy, the arranged marriage could make him realize he has responsibilities. He could become more committed to his music career as he wants to provide for Rachel and their future family. His rough edges would start to smooth out as he spends more time with Rachel, who has a more refined and goal - oriented personality.
