Their relationship might develop through shared experiences. For example, they could be working on a project together to save the wizarding world, and during that time, their feelings grow. The pregnancy would then deepen their bond as they start to think about building a family together.
The pregnancy could force them to communicate more openly. For example, they might have to discuss their future living arrangements. If Hermione wants to stay in the UK near her friends, Krum may need to consider relocating. This would lead to a deeper understanding of each other's needs and wants.
In some fanfictions, Hermione and Draco become friends through mutual understanding. Maybe they start to see beyond their house rivalries at Hogwarts. For example, they could be forced to work together on a special project for the school. At first, they might be hostile, but as they get to know each other's true selves, a friendship begins to form.
Well, it could develop through a shared experience outside of the typical Gryffindor - Slytherin rivalry. Suppose they both witness some dark magic activity in the Forbidden Forest. They have to rely on each other's strengths to get out of the situation. Hermione's vast knowledge of spells and Pansy's Slytherin cunning could combine in a way that makes them realize they are better off as friends. Their friendship might then grow as they keep this shared secret and start to trust each other more and more.
Often, it begins with Hermione trying to help Sirius deal with his post - Azkaban trauma. She uses her knowledge and compassion to reach out to him. As he heals, he starts to see her in a new light. Their relationship then grows as they start to understand each other better. The lemon parts usually are used to explore their more passionate and private moments, which are often written in a very tender and intense way, adding a new dimension to their relationship.
It could also develop with some tension. For example, if Jake is not ready for the pregnancy, there could be some arguments between them. But through these tough times, they learn more about each other and grow closer. They start to communicate better and by the end of the pregnancy, their relationship is stronger than ever.
Their relationship could develop deeper as they experience the pregnancy together. They become more in tune with each other's needs. Zayn might be more protective of Perrie, and Perrie could feel even more loved by Zayn.
If Hermione got pregnant, their relationship would be full of conflict. Tom has his dark past and tendencies. Hermione would be constantly worried about the influence he could have on the child. She would try to bring out the good in him, while he might struggle between his old ways and his newfound family. Their relationship would have to evolve as they face the challenges of raising a child in a world full of magic and danger. Tom might have to face his own demons more seriously to be a part of their family.
Some fanfictions develop their relationship through shared adventures outside of Hogwarts. They go on secret quests together, relying on each other's skills. Harry's courage and Hermione's intelligence complement each other during these adventures. As they face challenges and overcome them, their relationship blossoms into a romantic one while they keep it hidden from their friends.
In these fanfictions, writers first need to bridge the gap between their very different personalities and backgrounds. Since Hermione is intelligent and values justice, and Rodolphus was a Death Eater, there's a huge divide. The pregnancy could be the result of an unexpected event that then forces them to communicate. As they deal with the reality of the pregnancy, they might gradually learn to respect each other. Hermione could teach Rodolphus about redemption and he could show her a different side of the wizarding world she hadn't seen before. This way, their relationship grows from a forced coexistence due to the pregnancy to a more complex and nuanced bond.
In many of these fanfictions, their relationship often becomes more intense and reliant. For example, in stories where they are facing the mystery of Riddle together, they learn to trust each other even more deeply. They might start to rely on each other's unique skills, like Harry's courage and Hermione's intelligence, in a more profound way.
