Another possibility is that she focuses on protecting her family, especially Draco. She could be constantly worried about the after - effects of the war on him, like potential revenge from the side that won the war, and spends her time ensuring his safety and future.
Often, her character becomes more complex. She may question the beliefs she held before the war. For example, her loyalty to Voldemort was mainly due to her family's situation, and after the war, she starts to think if it was all worth it.
One possible scenario could be that Ron and Hermione focus on rebuilding the wizarding world. They might use their skills and knowledge to help repair Hogwarts. Hermione could be involved in reforming the Ministry of Magic's educational policies, while Ron might assist in ensuring the safety of magical creatures.
In Final Fantasy fanfiction, life after war could involve rebuilding shattered cities. Characters might focus on restoring infrastructure, like fixing broken bridges and reconstructing homes. There could also be a focus on healing the emotional scars of the war. Survivors may come together to form new communities, sharing resources and skills to create a better future.
One possible scenario could be in a post - war situation. Hermione might be feeling the after - effects of the war, the loss and trauma. Lucius, having lost a lot himself and perhaps having a change of heart, could offer her some words of comfort. He might share his own experiences of loss and how he's trying to rebuild his life, which in turn gives Hermione a new perspective on her own pain.
One possible scenario could be that Snape, now redeemed in the eyes of many after the truth about his actions during the war is known, might offer a simple apology to Hermione for any past harshness. He could be in a state of self - discovery and seeking to make amends with those he wronged in his guise as a Death Eater supporter. Hermione, being the empathetic person she is, might accept it graciously and they could have a brief conversation about the new world order post - war.
One possibility is that Hermione might initially be shocked and angry. Snape was not always kind to her during school, but now she realizes his true role in the war. She could confront him about his past behavior, yet also express gratitude for his sacrifices. For example, she might say something like 'I can't believe all you did, even after how you treated us at times.'
They might start a family. After the chaos of the war, they would likely want a peaceful and loving home environment to raise children in.
In the 'Harry Potter after the war story', perhaps Harry and his friends would focus on reforming the wizarding world's laws. There were a lot of unjust laws and practices that were brought to light during the war. They could work towards a more inclusive and fair society for all wizards and witches, regardless of blood status.
In this fanfic, it could also be that the bedroom has become a sanctuary of sorts. Despite the destruction outside, the couple in the story has made the bedroom a place of love and hope. They've decorated it with simple things they've salvaged, like a flower in a broken vase on the windowsill, symbolizing new beginnings.
In some fanfictions, they might go on adventures together. Exploring the wizarding world more fully, perhaps seeking out new magical creatures or ancient magic. They have a thirst for discovery after the chaos of the war. Harry's knowledge and Ginny's courage would make them a great team on these excursions.
