Perhaps Draco and Lucius find Hermione after she's been attacked by some dark creatures. Lucius might be more interested in using her injury to his advantage in the wizarding politics. But Draco, who has always had a bit of a soft spot for Hermione's intelligence and bravery, secretly tries to nurse her back to health. As Hermione recovers, she manages to outwit Lucius and also makes Draco question his family's allegiance to the Dark Lord.
Draco's relationship with Hermione could change drastically. He might start to feel sympathy for her, which could turn into a reluctant friendship. Lucius, however, would be more resistant to any positive change. But as Hermione shows her strength even while injured, he might develop a begrudging respect. Overall, Draco could become more of an ally to Hermione, while Lucius would be in a more complex situation of having to re - evaluate his views due to Draco's new attitude.
One possible plot development could be the aftermath of the one - night stand. Hermione might be filled with guilt and confusion, given her values and the fact that Lucius is on the 'enemy' side. Lucius, on the other hand, could be intrigued by Hermione's different nature and try to draw her further into his world, leading to a battle of wills between them.
Hermione herself would also develop. With the support of two former adversaries, she might gain more confidence in dealing with the pure - blood elite. She could learn to trust them and in turn, teach them things about the Muggle - born perspective. This triangular relationship could lead to all three characters growing in unexpected ways.
Perhaps Draco saves Hermione in a very public and unexpected way. This could lead to a huge scandal in the wizarding world. Lucius might be shamed and lose a lot of his influence among the Death Eaters. Draco, on the other hand, might find himself an outcast among his own family and former friends. Hermione, feeling indebted to Draco, might try to protect him from the backlash, which could further develop their relationship in an interesting way. It could also be that Draco's act of saving Hermione is part of a prophecy that neither of them knew about. This could add a layer of mystery and destiny to their story.
Perhaps it's a story where Draco is learning how to fly better from his father Lucius. Lucius could be showing Draco some advanced flying techniques while they are on the broom, and during the flight, they might have a deep conversation about the family's future in the wizarding society.
One possibility is that Lucius is trying to prepare Draco for a dangerous task in the wizarding world. He believes that by starving Draco, he can make him more resilient and focused. However, this extreme method backfires as Draco starts to lose his health and his magical abilities start to wane. His friends notice the change and try to intervene, leading to a conflict between Lucius and those who want to protect Draco.
Perhaps the kiss is a moment of impulse for Draco, who has been secretly attracted to Hermione's intelligence and courage all along. Hermione, on the other hand, is initially shocked but then realizes she has some feelings for Draco too. Their relationship could then develop as they try to find common ground between their different houses' values. They might start working together on a project in the library, away from the prying eyes of their classmates, and slowly build a deeper connection through their shared love for learning and magic.
In this scenario, it could also lead to a major shift in the relationships within the fanfiction. Hermione might feel betrayed if Draco doesn't stand up to his father. And Draco could be forced to make a difficult choice between his family's expectations and his feelings for Hermione. Lucius's interference could also bring in other elements of the wizarding world, like the Ministry or other pure - blood families getting involved depending on how the situation unfolds.
One possible plot could be that Lucius is trying to punish Draco for some disobedience or failure. Starving him could be a form of extreme discipline in a very dark and cruel Malfoy family dynamic.
One possible plot could be that Lucius is disappointed in Draco for not being as cruel or cold - hearted as he wants him to be. Lucius might try to toughen Draco up by putting him in difficult situations, like making him face a powerful dark creature alone. Draco, being scared and not ready for such a trial, starts to cry out of fear and a sense of being let down by his father.
