Maybe they are in the Forbidden Forest. They've gone there on a bit of an adventure together. As they hide from a group of centaurs passing by, they find themselves in a small, secluded nook. The danger and the secrecy of the situation heighten their emotions, and they start to make out, with the sounds of the forest around them adding to the excitement.
One possible scenario could be that they are in the Gryffindor common room. The fire is crackling, and everyone else has gone to bed. Harry and Ginny sit on the couch, and slowly start to get closer. Their eyes meet, and then they share a gentle kiss that gradually becomes more passionate as they let their feelings for each other take over.
One possible scenario could be that Harry finally finds the courage during a quiet moment at Hogwarts, perhaps in the Gryffindor common room by the fireplace. He might stutter a bit at first, but then clearly say his feelings. Another could be that it happens during a dangerous adventure when he realizes he can't hold his feelings in any longer, fearing he might lose Ginny. Maybe he confesses after Ginny has been in some sort of danger and he realizes how much she means to him.
In some fanfictions, it might occur during a trip on the Hogwarts Express. They are sitting in a compartment, just the two of them. The train is chugging along, and the scenery outside is passing by. Harry looks at Ginny and starts a conversation about their future. Then he casually asks if she would like to go on a date with him when they get back to Hogwarts. It could also be after Ginny has been in some sort of danger. Harry is so relieved when she's okay that he blurts out his feelings and asks her out.
One common scenario could be Ginny flirting with another boy in front of Harry. For example, she might dance with a popular Quidditch player at a Hogwarts party while Harry watches. Another could be Ginny getting a lot of attention from an older student for her academic achievements, and Harry starts to feel left out and jealous. Maybe Ginny is also asked to be a partner for a special project by someone other than Harry, and she seems really excited about it, which makes Harry green with envy.
A great scenario in a Ginny and Harry get married fanfic would be a destination wedding in a far - flung magical place. Maybe they choose a wizarding island where they can have the ceremony on the beach under a starlit sky filled with magical constellations. Another scenario could be that they get married in a rebuilt Hogwarts, with the castle being a symbol of their past and their future together. And then there could be a scenario where Ginny and Harry have a very modern - wizarding wedding, with new spells and charms being used for the decorations and entertainment that no one has seen before.
One possible scenario could be that Ginny and Harry are in the Gryffindor common room. Ginny has had a long day of Quidditch practice and studying. She sits next to Harry on the couch, and as they are chatting softly about their day, her eyes start to droop. Harry notices but doesn't want to disturb her, and soon she falls asleep on his shoulder. Harry then just sits there, feeling a warm sense of protectiveness and contentment.
One possible scenario could be Sirius noticing how Harry blushes whenever Ginny's name is mentioned. So he might say something like, 'Harry, I've seen you go redder than a Weasley's hair at the mention of Ginny.' Another could be if Ginny gives Harry a special gift, and Sirius teases him about it, 'Harry, that little present from Ginny must mean something special, eh?' A third scenario could be when Ginny is around and Harry acts a bit clumsy. Sirius would then joke, 'Harry, you're more out of sorts than a drunk Hippogriff when Ginny's near.'
One popular 'Harry and Ginny making out' fanfiction is 'The Hidden Moments' which beautifully captures their relationship. It delves into the tender and passionate moments between them. Another one could be 'Ginny's Heart' where the author portrays their love story with great detail, including some making - out scenes that are quite well - written. And 'Love in Hogwarts' also has some great scenes of Harry and Ginny's affectionate moments.
One possible scenario could be that Ginny meets an old acquaintance who has changed a great deal and she starts to have feelings for this person while still being with Harry. Maybe they share a common interest that she feels Harry doesn't understand. However, this goes against Ginny's strong character in the original series, so it's a very different take in fanfiction.
In some versions, it could be that Harry has to die to break a dark curse placed on Ginny. He discovers that his life is the key to saving her and willingly gives it up. He might have a premonition about Ginny's fate and decides that his death is the only way to change it. He then confronts the source of the curse and allows it to take his life instead of Ginny's.
