Eventually, they could form an unexpected bond. Through shared experiences within the marriage, like dealing with the wizarding society's reactions or facing common threats, they might find common ground. This could transform their relationship from one of forced association to a partnership of sorts, where they support each other in ways neither expected at the start.
As time passes, they might develop a grudging respect for each other. Harry would realize Severus's contributions to the wizarding world that he wasn't fully aware of before. Severus might see Harry's growth and maturity. This could lead to a more civil relationship where they communicate more openly, though still with some underlying tension.
At first, their relationship would be full of hostility. Harry would be angry about being forced into this marriage with Severus, who he has had a complex history with. Severus, on the other hand, might be indifferent or even disdainful.
At first, it would be extremely strained. Severus has a history of being at odds with Harry. But with the baby in the picture, they would be forced to interact. Harry might see a different side of Severus as he tries to be a father. Severus, on the other hand, would have to deal with his own feelings towards Harry while also caring for the baby. Over time, they could develop a bond based on their shared responsibility and the love for their child. This would be a huge transformation from their previous relationship which was full of mistrust and dislike.
Harry might develop from being resistant to the marriage to being more open - minded. He realizes that Severus is not just the strict teacher he once thought. For Severus, he may start to soften his tough exterior. He begins to see Harry not as James Potter's son but as an individual with his own merits.
One possible plot development could be that at first Harry is extremely resistant. He might try to find ways to break the forced marriage. Maybe he'll seek help from his friends like Hermione and Ron. They could try to look for magical laws or loopholes to dissolve the situation.
His personality also becomes more open. He has to communicate with Harry in a more honest and open way. He can't keep all his thoughts and feelings bottled up like he used to. He has to share his wisdom and experiences with Harry, which in turn makes him more approachable and less of the brooding, closed - off person he was before in the official story.
At first, it's likely to be full of tension. Harry may be hesitant and even a bit resentful about the marriage, while Severus is his usual cold self. But as time passes, they start to see each other's good sides. Harry realizes Severus's intelligence and Severus sees Harry's courage in a new light.
Severus would likely become more protective. His personality would shift from being mainly focused on his own grudges and potions work to being centered around Harry's well - being. He might also become a bit more open - minded as he has to consider Harry's needs and wants, which could be different from his own. For instance, he may have to tolerate Harry's love for flying, even though he himself may not be into it. And over time, he might develop a sense of humor as he deals with Harry's childish antics.
He would become more nurturing. Usually, Severus is seen as cold and aloof, but with Harry in his care, he'd have to show more warmth. He might still be strict, but it would be out of love for Harry's well - being rather than just being his usual harsh self.
In these fanfictions, they often explore the relationship by delving into the power dynamics at play. Severus, being a former Death Eater and a teacher, has a certain authority. Harry, on the other hand, is the Boy Who Lived. The lemon aspect adds a layer of passion and physicality. For example, in some stories, the initial animosity between them slowly turns into a more complex attraction. The fanfictions may use their shared experiences, like fighting Voldemort, as a backdrop to build this unique relationship.
In these fanfictions, the relationship often starts with a lot of tension. Harry may be suspicious of Severus at first, given their past in the original story. But as they spend more time together, they start to see each other in a new light. For example, Severus might show his softer side to Harry, like his love for potions and his hidden sense of humor. Harry, in turn, might show Severus his more mature and understanding side, different from the bratty kid Severus used to see.
The relationship may become more complicated. Severus might struggle with his own emotions. He might feel an urge to protect Harry from this fictional abuse, but at the same time, he has to deal with his long - standing animosity towards Harry. So, it could lead to a very strange and tense dynamic between them, with Severus trying to balance his new - found protectiveness and his old grudges.
