It could be that their pets are the unique supporting characters. If they have a dog or a cat, the pet could be part of the wedding in some cute way, like being the ring bearer. And during their daily life leading up to the wedding, the pet's presence could add some humorous and heartwarming moments as Bella and Paul plan their big day.
Their best friends could be great supporting characters. For example, Bella's best friend might help her with choosing the wedding dress, giving her advice on how to deal with pre - wedding jitters. Paul's friend could be the one who organizes a wild bachelor party but also stands by him during the nerve - wracking moments before the wedding.
One possible plot could be that Bella and Paul face family opposition at first. Maybe their families have some long - standing feud or different social statuses. But through their love and determination, they gradually make their families understand and finally have a grand wedding with all their loved ones present.
Their best friends could be great supporting characters. Maybe there's a friend named Lily who helps Emma with all the wedding preparations, from choosing the flowers to making sure the bridesmaids' dresses are perfect. And Xander could have a buddy, Tom, who gives him some pre - wedding pep talks and helps him with his suit fittings.
Jen could be another important supporting character. She could help Joey with all the wedding preparations. Jen would be the one to calm Joey's nerves when things get hectic, and she could also offer some great fashion advice for the big day. Maybe she also catches the bouquet at the wedding, which could lead to her own romantic sub - plot in the fanfiction.
Ash could be a supporting character. Ash, being the kind - hearted trainer he is, might visit Paul in the hospital. He could bring some special Pokemon items or just his own positive energy, which could annoy Paul at first but then start to have a positive effect on him.
Hermione and Ron would likely be important supporting characters. They could be involved in the wedding preparations, like Hermione helping Ginny choose her dress or Ron trying to keep Harry calm before the ceremony.
Ron could be a main supporting character. He might initially be a bit shocked but then comes to accept and support their relationship. He could be there to offer his humor and his own brand of wizarding skills when they are in trouble.
Mario would surely be a big part of it. He could be Luigi's best man, giving him advice on how to deal with pre - wedding jitters. Princess Peach might also be there, helping Daisy with her wedding dress and all the girly stuff. Toad could be the one in charge of the invitations, running around the Mushroom Kingdom to make sure everyone gets one.
Their parents or guardians could also be supporting characters. They could offer wisdom from their own experiences in marriage. For example, they could give advice on how to handle arguments or how to keep the romance alive in a long - term relationship.
Gray could be a supporting character. He might be a bit jealous at first but then becomes a good friend and helps Natsu out when he gets into trouble. Erza could also be there. She would be like an older sister figure, giving advice to Levy on how to handle Natsu's sometimes reckless behavior. Happy, Natsu's Exceed friend, would definitely be around, providing some comic relief and also helping them out in various situations.
Theodore could be a great supporting character. He could be the one who helps Alvin and Jeanette plan their wedding and then also gives them advice on how to handle married life. Simon could also be there, perhaps using his intelligence to solve any problems that come up in their relationship, like financial issues or misunderstandings with their neighbors.
