They find common interests outside of their initial differences. Maybe they both discover a love for cooking (even if Ranma is initially hesitant). Working together in the kitchen, they learn to cooperate and enjoy each other's company, which in turn helps them handle their different personalities in a more harmonious way.
They use their martial arts training as a way to bond. When they spar, they not only keep their skills sharp but also communicate on a deeper level. Through these sparring sessions, they learn to respect each other's strengths and weaknesses, which helps them deal with their different personalities in daily life.
They might handle family conflicts by first trying to communicate openly. Ranma could use his charm to smooth things over with Akane's family, while Akane would try to be more understanding of Ranma's family's quirks. For example, if Ranma's father causes some trouble, Akane might talk to him calmly and explain how his actions are affecting their family. And if Akane's sister gets jealous of the attention Akane is getting as a newlywed, Ranma could cheer her up with some martial arts tricks.
Sly is a laid - back, adventurous thief, while Carmelita is a by - the - book cop. In marriage, they'd have to learn to compromise. Sly might tone down his more reckless behavior, and Carmelita could be more open - minded about Sly's unorthodox methods. For example, when Sly wants to explore an old, abandoned building that might be illegal, Carmelita could find a legal way for them to do it.
There is a fanfic titled 'Ranma and Akane: Married Bliss'. In this, the story delves deep into how they adapt to living together as a married couple. It explores their cultural differences within their family settings. For example, how Ranma's martial arts family traditions blend or clash with Akane's more traditional family ways. They learn to make compromises and grow closer as a result.
Elizabeth's personality could develop in a way that she becomes more confident in her role as Mrs Darcy. She might start to take on more social responsibilities in their community, using her charm and wit to win over the local gentry. Mr Darcy's pride could soften further. He may be more willing to admit his mistakes in front of Elizabeth and learn from her. They both might also develop a stronger sense of humor together, sharing private jokes and light - hearted moments that help them grow closer as a couple.
They could use their powers to protect each other. Izuku's One For All power can be used to physically defend Toga, while Toga's shape - shifting ability can be used for stealth and gathering information. For example, she could transform into someone to infiltrate a dangerous place to help Izuku in his hero work.
One possible plot twist could be that they suddenly discover a long - lost family secret that threatens their marriage. For example, it could be revealed that their families have an ancient feud that was forgotten over time. Another twist might be that a new character arrives, someone from Ranma's past who claims to be his betrothed from a prior arrangement. This would create a lot of drama as Ranma and Akane would have to deal with this unexpected situation. Also, there could be a magical or supernatural element involved. Maybe a curse is placed on their marriage that makes them forget why they fell in love in the first place, and they have to go on a journey to rediscover their feelings.
After marriage, they may decide to gradually phase out their double identities. Selina might start to use her skills for more legitimate causes, like helping Bruce with his charity work in a more public way. Bruce, on the other hand, could start to focus more on the business side of Wayne Enterprises and less on being Batman all the time. But it wouldn't be an easy transition, and they would have to deal with the reactions of the people in Gotham who are used to seeing them as Batman and Catwoman.
In a Ranma and Akane baby fanfiction, it could explore the reactions of their friends and family. For example, Genma might be overbearing with his advice on raising the child. Nabiki could be scheming to make some money off the new addition to the family. And all the while, Ranma and Akane are just trying to figure out how to raise their baby in a world full of martial arts and magic.

Another plot could involve them having to deal with family drama before the wedding. Maybe Ranma's father has some outlandish requests or Akane's family has some concerns. But through it all, their love for each other prevails and they finally tie the knot in a beautiful ceremony by a cherry blossom tree.
