Yes, there are quite a few. You can start by looking on popular fanfiction websites like Fanfiction.net or Archive of Our Own. Just search for 'Harry and Hermione are Panthers' and you'll likely find some interesting reads.
One plot idea could be that they use magic to transport themselves to Panthers games and have to keep it a secret from the wizarding world. Another could be that they meet other Panther fans in the wizarding world and form a secret fan club.
Well, 'Secret Encounters' is a Severus and Harry lemon fanfiction that many fans seem to like. It has a good balance between the emotional connection and the more adult - themed interactions. But be aware that this kind of fanfiction isn't for everyone as it can be quite explicit in nature. There's also 'Forbidden Love's Flame' which takes their relationship to a new level of passion.
Hermione would probably be one of the main characters to interact. She might be horrified at first to see Harry in such a situation and would try to find a way to free him. Ron could also be involved, perhaps being more impulsive in his attempts to rescue Harry, which might cause some problems. Dumbledore too would likely play a role. He might have some knowledge about the situation that he's not sharing right away, and his interactions with Severus would be crucial in determining Harry's fate.
Lily Potter is often a significant character. Since she was friends with Severus in the past and is Harry's mother, she can play a crucial role in fanfictions. Her relationship with Severus and how it affects Harry can be explored in different ways, like through memories or magical connections.
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.
Hermione is often a popular character. She can play the role of the mediator or the one who tries to figure out what's really going on between Harry and Severus. For example, she might notice the strange new dynamic between them and try to use her intelligence to uncover the truth.
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.
