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.
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.
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.
Izuku could develop more confidence in his personal life. Since he's married to Momo, who is intelligent and strong, he might learn to rely on her more, not just in battles but also in decision - making. For example, when it comes to handling their finances or choosing a new place to live.
One possible storyline could be that they are in a committed relationship and the pregnancy is unexpected but they decide to face it together. They might struggle with how it will affect their hero careers and deal with the reactions of their friends and families.
Jackson could develop more patience. Since April might have her own quirks and ways of doing things, he would need to be more patient in their married life. For example, if she is very particular about how the house is organized. April could become more confident. With Jackson's support, she might feel more self - assured in her decisions, both in their relationship and in other aspects of her life. For instance, she could take on more leadership roles at work.
In this fanfiction, Setsuna might develop a new - found sense of stability. His relationship with Marina and their marriage gives him a home and a family in a sense. He could become more protective, not just of Marina but also of the life they are building together. Marina could develop a deeper understanding of Setsuna's past traumas and how they shape him. This understanding could lead her to be more empathetic and also help her in guiding Setsuna towards a more healed and whole self as they navigate their married life.
For Percy, he might become more responsible. Marriage would mean he has to think about not just himself and his friends, but also his partner Reyna. He could develop better leadership skills as he and Reyna might need to lead their family or even the demigod community together. Reyna, on the other hand, could become more open - hearted. She has always been a bit guarded, but with Percy as her husband, she might let her walls down more often. She may also develop a softer side, especially when it comes to dealing with Percy's more impulsive nature.
Domon might become more gentle and understanding as he adapts to married life with Rain. He could learn to communicate better and be more open about his feelings.
Winter might become more open and less rigid. Being married to Jaune, who is more carefree, could encourage her to let loose a bit and show her softer side more often. For example, she might start to enjoy simple pleasures like picnics, which she never considered before.
