In some fanfiction, it could be due to a prophecy. A seer might have predicted that their union, though forced at first, would bring great things to the wizarding world. So, the wizarding authorities or some powerful wizards force them into an engagement. Hermione would be the one to try and find a logical solution, using her vast knowledge of magic and history. Viktor would use his physical strength and his own knowledge of different magical cultures to help. They might start off as reluctant partners but gradually develop a bond as they face various challenges together, like threats from dark wizards who don't want the prophecy to come true.
In the fanfiction, Draco could be an observer. He might not directly interfere with Hermione and Viktor's relationship but instead watch from afar. He could be in a state of self - reflection, comparing their relationship to his own past relationships or his family's view on love and marriage. As he observes, he might learn something about himself and his own capacity for love, and this could lead to his own character growth without directly involving himself in Hermione and Viktor's engagement.
Hermione's friends would have a range of reactions. Ginny might be sympathetic towards Hermione, understanding the difficult position she's in. Neville could be worried about how this would affect Hermione's studies and her role in the fight against the dark forces. For Viktor's friends, they might try to encourage him to make the best of the situation. His Quidditch teammates might see it as an opportunity for Viktor to show his maturity and handle a complex situation. However, some of his closer friends might also be worried that he's getting involved in something that could end badly for him.
Perhaps in the fanfiction, they get engaged in a very magical setting, like on top of a floating mountain in Bulgaria. Then they have to plan a wedding that combines both wizarding cultures, which is full of challenges and fun cultural exchanges.
To develop their relationship, you can start with their shared love for magic and Quidditch. They could have deep conversations about different magical techniques and how they can improve their skills together.
Well, it could be that in the fanfiction, Hermione travels to Bulgaria for a magical research project. There, she meets Viktor again. They team up to solve a mystery that has been plaguing the Bulgarian wizarding world. As they do so, their relationship deepens and they have a baby. The story could then be about how they protect their child from the dark forces that were involved in the mystery they solved.
One possible plotline could be that it's a political arrangement. Maybe in the wizarding world, there are political tensions between their respective countries, and a forced marriage is seen as a way to ease those tensions. Viktor and Hermione would then have to figure out how to live with each other while also dealing with their own personal feelings and the expectations of their countries.
One possibility could be that Draco is jealous. In many fanfictions, Draco has an unspoken or even a growing admiration for Hermione. If she's engaged to Viktor, Draco might feel a sense of loss or envy. He could try to interfere in their relationship in a rather sneaky way, perhaps by spreading rumors about Viktor's past. Another idea is that Draco actually helps them in some unexpected way. Maybe he realizes that Hermione is truly happy with Viktor and, despite his own feelings, decides to be the bigger person and support them. For example, he could use his influence in the wizarding world to help Viktor with some career - related issues, which in turn benefits Hermione and their relationship.
In some fanfiction, if Draco forces Hermione to marry him, it could lead to a very dark and complex storyline. Hermione, being a strong - willed character, would likely fight back in some way. Maybe she'd initially resist and try to escape. It could also involve other characters like Harry and Ron coming to her rescue. However, some fanfic authors might explore a more nuanced relationship where over time, Hermione might find unexpected understanding or even a strange connection with Draco despite the forced start.
One way it could develop is if Dumbledore withholds important information from Hermione about her family or her own magical abilities. He might do this because he fears she will use that knowledge in a way that could disrupt his grand plan for the wizarding world. For instance, Hermione discovers she has a special power that could defeat Voldemort easily, but Dumbledore has kept it from her all along, making her feel extremely betrayed as she could have saved many lives if she knew earlier.
Well, their relationships can develop in many ways. For example, Viktor Krum might start by sending Hermione letters from Bulgaria. At first, Hermione might be hesitant to respond, but as time goes on, she starts to write back. Harry could be a bit jealous at first, thinking Krum is trying to steal his friend. But as he sees how happy Hermione is, he starts to accept it. Then, when they meet again in person, the feelings between Hermione and Krum become more intense.
