Well, it could start with Ochako being the one to initiate the relationship towards marriage. She might feel that she and Izuku have a special bond that goes beyond friendship. Izuku, being a bit shy at first, takes some time to fully embrace the idea but then realizes he can't imagine his life without her. For the wedding, it could be a big event where all the different hero academies come together to celebrate. In their married life, they could have a friendly competition about who can save more people in a year. And they also help train the new generation of heroes together, passing on their values and skills as a married hero couple.
The plot might involve Izuku and Ochako having to overcome some obstacles before getting married. Maybe there are some villains who target them because of their relationship, thinking that a married hero couple could be a big threat. So they have to fight these villains together and prove that their love is stronger than any threat. Once they get married, they might go on a honeymoon to a secluded place, like a small island. There, they can relax and just be a normal couple for a while, away from the chaos of the hero world. And when they return, they are even more determined to make a positive impact on the world as a married couple.
Well, their wedding would be unique. Since they are both heroes, they might incorporate elements of their hero personas into the wedding. Maybe the cake could be designed like one of Izuku's attacks or Ochako's Zero Gravity ability. The guests would include all their classmates from UA, and they would all share stories about Izuku and Ochako's time at school. The ceremony would be full of love and laughter, with Izuku and Ochako exchanging heartfelt vows.
The plot could involve a post - war scenario. After all the chaos, Toga and Izuku find solace in each other. Toga might have had a change of heart during the battles and Izuku, being the empathetic person he is, sees the good in her. They get married secretly at first, and then gradually try to make their relationship known. Their union could be a symbol of hope for a new era where people are not just defined by their past actions but by their potential for change.
One possible plot twist could be that Izuku suddenly loses his powers right before the wedding. This would add a lot of drama as they have to figure out how to deal with this new situation. Momo might have to use her intelligence and creativity to find a way to get Izuku's powers back or to help him adapt to a powerless life. Another plot twist could be that a villain kidnaps Momo on the wedding day, and Izuku has to go on a rescue mission, showing his heroic side even on his big day.
Some fanfictions might include Uraraka's family members. Her parents could be involved in their married life, for example, giving Ochako traditional family advice. Also, Izuku's mother could be a prominent character, sharing her own experiences of being a single mother and now seeing her son happily married.
One interesting plotline could be their journey in starting a family. They might face challenges like Izuku's hero duties interfering with family time, but they work through it together. Another could be them renovating their first home as a married couple, with Ochako having creative ideas and Izuku using his strength to help.
For Izuku, he might become more confident in his personal life. Marriage to Ochako gives him a sense of stability and he starts to show more leadership not just in hero work but also in his family life. He could also become more expressive of his emotions. Ochako, on the other hand, may develop a stronger sense of responsibility towards their relationship. She might be more assertive in her decisions and support Izuku in a more vocal way. For example, when Izuku is doubting himself in a tough hero mission, Ochako is there to boost his confidence.
One idea could be that they have to overcome the differences in their backgrounds. Izuku is a hero - in - training from a more traditional hero - minded society, while Toga is from a villainous group. Their love could be the catalyst for change in both the hero and villain worlds, as they try to find a way to coexist and be together.
It could occur during a time of self - discovery for both of them. They've been through a lot together and have grown closer. One day, while they're having a deep conversation about their dreams and feelings, Izuku realizes how much Ochako means to him. He nervously approaches her, and their first kiss is a slow and gentle exploration of their new - found romantic feelings.
Well, there could be a lot of awkwardness. Maybe Izuku's parents would be overly excited to meet Ochako, asking her all sorts of questions about her quirk and her life. And Ochako's parents might be a bit protective at first, sizing Izuku up to see if he's good enough for their daughter. It could also be a really heartwarming moment, with the parents realizing how much the two care for each other.
One great izuku and ochako fanfiction is 'A New Beginning'. It shows their relationship development in a really sweet way. They face challenges together and support each other, and the author does a wonderful job of capturing their personalities.
