Hermione might become a reclusive healer. Changing her identity to that of a healer who lives in a hidden cottage in the woods. She would keep her identity a secret and only help those who stumble upon her cottage. This new identity would give her the chance to focus on her study of magical healing in peace, away from the chaos of the wizarding world she knew before.
Another plot could be Hermione changing her identity because she is wrongly accused of a crime. She decides to assume a new identity to clear her name. In this new identity, she travels to different magical communities, looking for evidence that can prove her innocence. Along the way, she meets new characters and has various adventures.
I recommend the novel " The Emperor of the Phoenix's Concubine's Beauty ". The male protagonist brought the memories of his previous life back to the beginning, expanding his power step by step, and finally marrying the female protagonist as a princess. The novel had a double life plot. Both the male and female leads had a lot of scenes and were very sweet. The male lead was a white and black character. From the beginning, he was devoted to the female lead and loved her very much. I hope you like my recommendation.😗
It could be a dark wizard who discovers Hermione's hidden identity and wants to use it for his own evil purposes. Maybe he wants to harness the power that comes with her true identity to take over the wizarding world.
There's also a possibility that it could be a minor Death Eater that we don't know much about from the original series. The author of the fanfiction could create a new character who was a Death Eater but is now having doubts. Hermione could be the one to find this person and start their journey of change. This would give the author a lot of creative freedom to develop the character's backstory and their relationship with Hermione.
There's a possibility she meets a group of young Italian wizards and witches who are part of a secret magical society. They are dedicated to protecting the hidden magical places in Italy. Hermione gets involved with them and helps in their quests, while also learning a great deal about Italian magic and culture from them.
She could meet her future self. This would be an interesting encounter as they could compare their experiences and knowledge. Her future self might give her some advice on things she should do or avoid in her own time. Another person she could meet is a descendant of her friends. For example, a grandchild of Harry and Ginny who has inherited their bravery and magical skills.
The Goddess of Rebirth's Counterattack and The Return of the Real Daughter were two novels that fit the plot of the identity swap. The female protagonists of these novels had their identities secretly changed after their rebirth. They experienced a series of counterattacks and growth, and finally became the masters of their own destiny. Among them, the female lead of " The Goddess of Rebirth's Counterattack ", Yun Luo, was brought abroad by her adoptive mother to live. After she was killed, she was reborn and returned to her original identity, becoming a celebrity in the entertainment industry. The female lead of " The Real Miss Is Back ", Su Mo, returned to reality after completing the task assigned by the system. She found that an outsider's soul had entered her body and messed up her life. However, she reversed her fate through hard work and wisdom and became one of the best in the entertainment industry. These novels all revolved around the struggles and counterattacks of the female protagonists, showing the story of their identities being secretly swapped to their successful counterattacks.
Harry and Ron could become her surrogate family. They are her closest friends, and in the absence of her real family, they would likely step up. They already share so many experiences together, and this could deepen their bond to a family - like level.
McGonagall could be her coach. McGonagall is strict and has high standards, which would push Hermione to be the best she could be in gymnastics. She could use her Transfiguration skills to create unique training equipment for Hermione.
Another idea is that she changes her look as part of a self - discovery journey. She might decide to cut her hair short and start wearing more modern - looking wizarding robes, which causes a stir among her friends. Some of them are initially shocked, but as they see her new confidence, they come to accept and admire her new look.
