Another way she could deal with it is by trying to get Ron to improve in the areas her parents dislike. For example, if they think he's too lazy in his studies, Hermione could encourage Ron to be more studious. This way, she can show her parents that Ron is making an effort to be a better person and a more suitable partner for her.
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.
He might crack a joke. Ron has a knack for using humor in tough situations. Something silly to make her laugh and forget her troubles for a moment.
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.
She might be heartbroken. Hermione is a strong - willed character, but being cheated on would surely shatter her. She could initially be in disbelief, given her trust in Ron. Then, she might become angry and start to distance herself from Ron, focusing more on her own studies or other relationships, like her friendship with Sirius.
In many fanfics, their relationship develops through shared hardships during the search for Horcruxes. They rely on each other more and more, which deepens their emotional connection.
In some fanfics, Hermione's abusive parents might be shown as neglectful. They could be constantly criticizing her intelligence or magical abilities. For example, they might not understand her love for books and learning magic, and instead push her towards more'muggle' - appropriate activities. This creates a contrast to her life at Hogwarts where she is celebrated for her brains.
He might try to be a good friend first. In many cases in fanfics like this, Harry would suppress his feelings and focus on the friendship. He doesn't want to lose Hermione as a friend just because of his love, so he might choose to be there for her whenever she needs, whether it's for schoolwork or facing Voldemort.
Some fanfictions might have Hermione immediately cut Ron out of her life. She's a strong - willed character, and such a hurtful comment could be the last straw. This would then lead to a story about her moving on without him and finding new friends or allies.
In this fanfic, the relationship between Hermione and Ron might be explored through the eyes of other characters. For instance, Harry might notice the small glances and touches between them that he hadn't paid much attention to before. It could also show how their relationship affects the group dynamic. With Hermione choosing Ron, it changes the way the trio interacts. And it could explore their future together, imagining how they would build a life as a couple in the wizarding world, dealing with things like family, career, and their place in the wizarding society.
In fanfic, the relationship between Hermione's parents and Harry might be more formal and respectful. Since Harry is the famous 'Boy Who Lived', they might treat him with a bit more deference. With Ron, they might see him as more of a regular kid, as he doesn't have the same level of fame. So, the relationship could be more casual.
