Well, it depends on what you consider 'good'. There are stories that take the idea of Harry and Hermione in a harem scenario and really run with it. They might incorporate different elements from the Harry Potter universe, like new spells or hidden magical places. However, not all of them are well - written. Some might have inconsistent characterizations. But if you dig around, you can find some gems that handle the concept in an interesting way.
One common theme is the exploration of polyamorous relationships. It shows how Harry and Hermione can be in a relationship with multiple characters and how they all interact. Another theme is often power dynamics, as some characters in the harem might have different levels of magical ability or social status.
Ginny Weasley could be a likely candidate. She already has a connection with Harry in the original series. Luna Lovegood might also be included. Her unique perspective and kind nature could make her an interesting addition. Cho Chang could be another possibility as she and Harry had some romantic history before. And maybe even some of the lesser - known witches from different houses who admire Harry for his heroic deeds.
In the fanfiction, perhaps Hermione first makes a list of all the characters in the Harry Potter universe who she thinks would be a good match for Harry. She then starts to subtly nudge them towards Harry. For example, she might invite Ginny, Luna, and Cho to a study group with Harry, and gradually, feelings start to develop among them. She could also be the one to smooth out any misunderstandings or rivalries that might occur between the girls vying for Harry's attention.
Common themes in 'Harry Hermione Harem Fanfic' are quite diverse. There's often the theme of self - discovery for both Harry and Hermione as they deal with multiple romantic interests. The idea of unity within the harem against external threats is also seen. Additionally, some fics may explore themes of jealousy and how the characters handle it within the harem. Cultural differences within the wizarding world can also be a theme, as different characters from various backgrounds come together in the harem, and they have to bridge those cultural gaps.
In many fanfictions, Harry might comfort Hermione by simply being there for her. He could sit quietly beside her while she's upset, offering his silent support. Maybe he'll hold her hand gently to let her know she's not alone.
When it comes to 'Harry Hermione Harem Fanfic', it's important to note that different writers will have different takes on the concept. Some may focus more on the romantic aspects between Harry and Hermione while building the harem around them in a more subtle way. Others might go for a more action - packed story where the harem is formed due to certain events in the wizarding world. You can start by looking at the most popular ones on the fanfic sites and then explore from there based on what you like in a story.
Another theme is friendship. Even though it's a reverse harem situation, Hermione's friendships with other characters, like Harry and Ron, still play an important role. The fics usually show how these friendships are affected or enhanced by her new relationships. It's often a balance between romantic love and platonic love.
I really like 'Hermione's Harem of Hearts'. In this fanfiction, Hermione finds herself in a complex web of relationships with multiple characters. It explores her growth as a character while dealing with the affections of those in her reverse harem. It's full of emotional depth and some really sweet moments.
In some fanfictions, Harry might be overprotective of Hermione because of their strong friendship. They've been through so many dangerous situations together in the original story. Harry values Hermione deeply and has seen how vulnerable she can be at times, so he feels the need to protect her.
