A possible storyline is that Hermione is being hunted by dark forces because of her connection to the Notts. The Notts could be involved in some dark wizarding affairs, and now that Hermione's true identity is starting to surface, she becomes a target. She has to rely on her wits and the help of her friends to stay alive and uncover the truth about her family. This could also involve her learning new and dangerous magic that is associated with the Nott family, which could either help her or put her in more danger. And as she gets closer to the truth, she realizes that there are secrets within secrets in the Nott family history.
One potential storyline could be Hermione's discovery of her true heritage. She might start noticing strange similarities between herself and the Notts, or find some hidden family heirlooms. This could lead to a journey of self - discovery as she tries to figure out why she was kept away from her true family. Another storyline could involve the reaction of her friends, especially Harry and Ron. They might be initially shocked and skeptical, but then support Hermione as she delves deeper into her past. The Notts, on the other hand, could be conflicted about accepting Hermione, especially if they have different beliefs or values.
There could be a storyline where Hermione uses her new - found family connection to the Notts to bring about change in the wizarding world. If the Notts are a pure - blood family with a lot of influence, Hermione could try to convince them to be more accepting of muggle - borns. She could start by trying to change the views within her own family and then expand her efforts to the wider wizarding community. This would not be easy as she would face a lot of resistance, but with her determination and the power of friendship, she could make a real difference. Along the way, she might also discover long - forgotten family magic that could be used for good in the wizarding world.
