The plot might revolve around how Harry and Hermione discover they are having a baby. It could be an unexpected event. Then, they start preparing for the baby's arrival. Hermione would be researching all the best magical parenting books and spells, while Harry is more focused on making sure their home is safe. They might also worry about how the baby will be accepted in the wizarding community given their unique situation of being two of the most famous wizards who were not originally a couple in the main story.
One possible plot twist could be that the baby has some unique magical abilities that neither Severus nor Hermione expected. Maybe the baby can communicate with magical creatures in a way no one has seen before. This could lead to all kinds of adventures as they try to understand and control this new ability.
One possible plot could be the anticipation and preparation for the baby. Harry and Ginny might be seen discussing names, decorating the nursery. They could also face some challenges like dealing with the media attention, as Harry is famous. Ginny would be experiencing the physical and emotional changes of pregnancy, and Harry would be there to support her every step of the way.
One possible story line could be that they discover they have feelings for each other later in life, after all their adventures at Hogwarts. They get married secretly and then have a baby. The baby might inherit some very unique magical abilities, a combination of Harry's courage - related magic and Hermione's intellectual magic. And they have to protect the baby from the dark forces that still lurk in the wizarding world, just like they had to protect themselves when they were young.
One possible plot could be that the baby sister has some unique magical abilities from the start. Maybe she can communicate with magical creatures in a way that no one else can. This could lead to all sorts of adventures where Harry and his friends have to protect her from those who might want to use her abilities for evil. For example, Voldemort's remaining followers might see her as a new threat or a tool to be used.
One possible plot could be that Harry and Hermione find an orphaned baby during their post - Hogwarts adventures. They decide to take the baby in and raise it as their own. Along the way, they face challenges like protecting the baby from dark forces that might be interested in the child's potential magic. They also have to balance their own relationship and the new addition to their family life.
In this fanfiction, the plot could start with Harry and Hermione realizing that they want to start a family together in a non - traditional way. They find a baby who has some special powers or a mysterious background. As they adopt the baby, they have to figure out how to raise it while also juggling their own lives as important figures in the wizarding world. They may need to seek help from their friends like Ron and Ginny to create a stable and loving environment for the baby.
A possible plot is that they discover the baby has a very rare magical ability. This leads them on a journey to find out more about it. Maybe they have to travel to a far - off wizarding land where they meet other witches and wizards with similar powers. Along the way, they face challenges like protecting the baby from those who might want to use its power for bad. Also, the baby could bring Ron and Hermione closer as they work together to figure out this mystery about their child.
One way could be through a time - travel or alternate reality plot device. Maybe in a world where dark and light magic collide in unexpected ways, Harry and Bellatrix are forced to work together and somehow, against all odds, a connection forms that leads to a child. It would be a very complex relationship, full of inner turmoil for both characters.
Well, the plot could involve Natsu and Lucy finding out they're going to have a baby. Maybe at first they're shocked but then super excited. They could start preparing a nursery in their home, with Natsu using his fire magic to keep the room warm in a safe way. And they'd have to deal with the reactions of their friends, like Happy being overjoyed and Erza being the protective aunt figure.
I'm not sure if there is such a fanfiction. Fanfiction can cover a vast range of wild and creative ideas, but this particular concept seems rather unusual and might not be a common one. It could potentially exist in some niche corners of the fanfiction world, but I haven't come across it personally.
