It could be her sense of justice. If she believes that Harry is being wrongly accused of something or is being targeted unfairly, she'll leave the Burrow to stand by his side. For example, if the wizarding world starts to turn against Harry due to false rumors spread by the Death Eaters, Hermione would be there for him.
Her thirst for knowledge and adventure might also play a role. She might have found out about some ancient magic or a hidden place that she thinks Harry would be interested in. So she leaves the Burrow to seek him out and embark on this new discovery together.
Love could be her motivation. Not necessarily romantic love, but the deep friendship and care she has for Harry. She might sense that he's in trouble or just needs her support.
In such a fanfiction, one possibility is that Hermione leaves the Burrow to bring Harry some important information. Maybe she's discovered a new lead on the Horcruxes. She could be racing against time to reach Harry before Voldemort's forces find out about it too.
She could start by sharing more of her interests with the Weasley family. For instance, if she talks about her love for books and learning, she might find some common ground with some of the family members. Ginny, for example, might be interested in the more academic topics Hermione likes.
The 'Hermione Heals at the Burrow' fanfiction probably has a story full of care and recovery. Hermione may have faced some difficult situation before arriving at the Burrow. Once there, the family would rally around her. Ginny could be her confidante, sharing secrets and helping her deal with any emotional turmoil. The twins might use their humor to cheer her up. And all the while, Hermione is slowly but surely getting back to her strong self with the love and support of the Burrow's inhabitants.
In this fanfiction, the entire Weasley family could be involved in helping Hermione. Ginny, being Hermione's friend, would surely be there for her. They could talk about their experiences and Ginny could give Hermione the emotional support she needs. The Weasley boys, too. Fred and George might use their unique brand of magic to bring some cheer to Hermione's recovery. Ron, of course, would be by her side as well, perhaps feeling guilty if he thinks he had a part in her getting hurt.
Well, it could be about their simple daily life at the Burrow. Maybe they are helping Mrs. Weasley with the housework, and there are some cute and funny moments between them, like Ron accidentally messing up a spell while trying to assist Hermione in cleaning the dishes.
It's difficult to say if it's popular. Just from the title, it doesn't seem to be a widely known one that comes up in general discussions about popular fanfictions. However, it could be very popular within a niche group of fans who are interested in the particular characters and the setting of the Burrow, but without looking at things like views, reviews, and rankings on fanfiction sites, we can't be sure.
One common theme is friendship. When Ron leaves, it often tests the strength of Harry and Hermione's bond. They might have to re - evaluate what their friendship means without Ron. Another theme is growth. Harry and Hermione usually grow as individuals in these fics. They become more self - reliant and learn new skills or gain new insights.
One possible motivation is a sense of morality that Draco has buried deep inside. Despite his upbringing in a family of Death Eaters, he still has a conscience. Seeing Greyback about to harm Hermione, who is essentially an innocent in the face of such a brutal werewolf, stirs that conscience. Another factor could be his own self - interest. He might realize that by saving Hermione, he could gain some sort of leverage or protection in the complex world of the wizarding war.
Love. In fanfictions, it's a common motivation. Draco might have fallen in love with Hermione over time, and that love drives him to risk his life to save her from Voldemort.
Well, it could be that there's a misunderstanding. Hermione is a very intelligent and passionate character. She might have misinterpreted something that happened at the Burrow. For example, a comment made by Mrs. Weasley that Hermione took the wrong way. It could have been something as simple as a suggestion about her relationship with Ron that Hermione thought was over - stepping. So, in her characteristic strong - willed way, she storms out, leaving everyone at the Burrow a bit shocked and setting the stage for a story of reconciliation or further conflict.
