One possible plot could be that Hermione is captured and brought to the Malfoy Manor. Draco, having some internal conflict due to his growing feelings for Hermione despite their past enmity, tries to protect her from the other Death Eaters in the Manor. Maybe they end up having to work together to escape some dark magic trap set within the Manor.
In fanfics where Hermione is Draco's mate in Malfoy Manor, it could begin with a situation where Hermione discovers a side of Draco that no one else has. Maybe he shows a bit of kindness towards her when she's in a vulnerable position at the Manor. This small act could make Hermione re - evaluate her view of him. At the same time, Draco might be intrigued by Hermione's intelligence and tenacity. Over time, these feelings grow and they become mates, often defying the social norms of the wizarding world.
A really interesting scenario would be if they are trapped in a magically sealed room in the Manor. With no way out, they are forced to talk about their past misunderstandings. As they do, they realize how much they misjudged each other. They also find some old potions ingredients in the room and Hermione, being brilliant at potions, tries to brew a way out while Draco assists her in a rather clumsy but endearing way.
One thing that makes it interesting is the contrast between their backgrounds. Hermione, a Muggle - born with strong values of equality and knowledge, and Draco, a pure - blood from a family with a long history of prejudice. When they come together as mates in the context of Malfoy Manor, it creates a lot of tension and potential for character growth. They have to overcome their initial differences and the expectations of their respective social groups.
One possible scenario could be that Draco has a change of heart at Malfoy Manor. He might secretly try to protect Hermione from the other Death Eaters. Maybe he uses his knowledge of the manor's secrets to hide her or mislead the others. For example, he could tell them she escaped through a certain passage when in fact he has her hidden in a secret room.
Well, in such a fanfic, it might show how Draco and Hermione's relationship evolves over time. It could start with them being at odds due to their different houses and family backgrounds. But as the story progresses, they might find common ground. For example, they could both be interested in a particular area of magic that forces them to work together, and through that, their feelings start to change.

Both are under a great deal of pressure - Draco to please his family and uphold the Malfoy name, and Hermione to fight against the Dark forces.
