When Ginny touches it along with Harry, they are both pulled into the memory. There, Ginny gets to meet his parents in their younger days. They might mistake Ginny for a friend of Harry's from their time, and Ginny has to explain the situation while also getting to know Harry's parents better.
One possible plot could be that through some time - traveling magic, James and Lily are brought to the future where they meet Harry and Ginny.

They share stories of the past and the challenges they faced, and James and Lily get to see the world they sacrificed so much for in a new light.
One possibility is that they meet in Diagon Alley. Maybe Ginny is there with her family, getting her school supplies, and Harry just happens to be in the same shop.

In some fanfictions, it could be a really awkward encounter. Harry might feel a bit of tension since he has a history with Cho and is now with Ginny.

In fanfiction, when Harry and Ginny meet the Dursleys, there could be a lot of tension. The Dursleys are not fond of anything related to magic.

Harry, on the other hand, would be in an awkward position as he has to deal with his Muggle family and his magical girlfriend at the same time. There could be some humorous exchanges as Ginny tries to understand the strange Muggle world of the Dursleys while also showing them that magic is not something to be feared.
One scenario could be that they meet in a time - travel situation. Harry and Ginny could be transported back in time to when Lily and James were alive. There, they would get to know each other in a different way. Harry would finally be able to have a proper conversation with his parents. They could discuss the future, the prophecy, and how Harry has changed the wizarding world. Ginny could bond with Lily over their love for Harry and their Gryffindor spirit. It would be a very emotional and magical encounter.

Ginny, being a big fan of the stories she's heard about them, is initially star - struck. Lily and James are a bit confused by this strange girl but soon become friendly. They could all end up having an adventure together, perhaps trying to stop a small - scale dark magic incident in Hogwarts that Ginny knows about from history books.
In this fanfiction's afterlife, Harry and Ginny might be in a place where time has no meaning. They could be constantly surrounded by a warm, golden light that represents all the love and positive energy they've created during their lives. They start to discover hidden powers within themselves that allow them to shape the afterlife realm. For example, they might create beautiful gardens filled with magical plants that only exist in their memories from Hogwarts.
