Most fanfictions that focus on Ron and Hermione tend to center around their emotional connection, friendship, and the development of their romantic relationship in a more tasteful and respectful manner. A scenario like 'Ron kisses Hermione in her bra' goes against the general spirit of the original Harry Potter series which emphasizes values like friendship, loyalty, and love in a more innocent sense.
One possible plotline could be a situation where Hermione loses her bra during an adventure with Ron and there's some comical or awkward moments as they try to deal with it without others noticing. Another could be that Ron accidentally sees Hermione's bra and it causes some blushing and confusion between them as they realize their growing feelings for each other in a new light.
There's also 'The Unspoken Attraction' which focuses on Hermione's internal struggle with her feelings for Ron. It's a slow - burn story that makes the moment when Ron finally kisses Hermione all the more satisfying. The story delves deep into their characters and how they've changed since the early days at Hogwarts.
There might be some kind of misunderstanding. For example, Ron could have been misinformed about Hermione's actions. He thought she betrayed him in some way, like sharing Gryffindor's secrets with Slytherins, so he lashes out at her.
I'm not aware of any specific 'Ron and Hermione bra fanfiction' as it's a rather unusual and not very common theme. However, you can try searching on fanfiction websites like FanFiction.net or Archive of Our Own. Use the search terms 'Ron and Hermione' and see if any stories come up that might have a plot related to what you're looking for.
Another reason is that fans are often passionate about the idea of Ron and Hermione as a couple. Writing fanfiction about their kisses and relationship is a way to celebrate that couple. It gives them a chance to delve deeper into the emotions and interactions between the two characters, exploring things like how Ron might be nervous before kissing Hermione or how Hermione's logical mind reacts to the sudden rush of emotions during the kiss.
Hermione could also distance herself from her parents a bit. If they are too stubborn in their hatred, she might choose to be with Ron regardless and limit her interactions with her parents until they come around. After all, she's a strong - willed character and won't let her parents' opinions control her completely.
Another way Severus could save Hermione is by using his knowledge of the Dark Arts in a positive way. If she was hurt by a Dark spell from Ron (in the context of the fanfic), Severus might be able to counteract the spell's effects. He has extensive experience with Dark Arts spells, so he could figure out what spell Ron used and then use a counter - spell to reverse the damage.
Well, he could use his magic skills. Maybe he casts a powerful spell on Ron to stop him and then takes Hermione to a safe place, like Hogwarts where there are protective enchantments.
