Another scenario is when Hermione is getting attention from other male students at Hogwarts. Maybe she's being praised for her academic achievements, and some other smart students start to show an interest in her. Draco, who has his own feelings for Hermione, will get jealous and might try to outdo those students in some way to get Hermione's attention back.
A common scenario is when Hermione is getting along well with Harry or Ron. Since Draco has a complex relationship with them, seeing Hermione so friendly with them can make him extremely jealous. For example, in some fanfics, when Hermione is laughing and joking with Harry during a party, Draco can't help but feel a pang of jealousy.
Love - hate relationships are also very common. Draco's jealousy can be a sign of his hidden feelings for Hermione. He might act mean or try to sabotage her relationships, but deep down, he's in love. This creates a lot of tension and drama in the stories.
A popular one is 'Manacled'. Draco's jealousy is subtly shown as he watches Hermione interact with others. It's not always blatant, but you can see it in his actions and the way he tries to monopolize her time. The author does a great job of using this jealousy to build the relationship between the two characters.

One possible scenario could be a tense encounter. Mrs. Granger, being Hermione's mother, might be initially very suspicious of Draco. Given their families' past differences in the wizarding world, she could be cold towards him at first. But Draco, trying to prove he has changed, might be polite and respectful, which could gradually thaw Mrs. Granger's attitude.
One common plotline is that Draco gets hurt during a conflict, like a battle against Death Eaters or other dark wizards.

Then Hermione has to step in and help him, which leads to a change in their relationship.

For example, in many fics, Draco initially hates what he has become and tries to hide it, but Hermione helps him see that he is still the same person deep down. Another theme is the struggle against prejudice. The wizarding world often looks down on werewolves, and Draco and Hermione have to fight this discrimination.
Another scenario is during dangerous magical experiments or when they are exploring old, dangerous parts of Hogwarts. Draco, being more familiar with the darker aspects of magic in some cases, will be protective of Hermione who is always eager to learn and might not fully grasp the risks. In these fanfictions, he'll stop her from doing something too risky or help her out when things go wrong.
One common scenario is in school settings. When other students are bullying Harry or trying to harm him, Draco steps in to protect. Another could be during dangerous magical events. For instance, when a dark magic spell is about to hit Harry, Draco uses his own magic to shield Harry.
