Another scenario might be them participating in a Hogwarts event, like the Yule Ball, as a couple. They would dance together, and Harry would be completely smitten with Ginny as they twirl around the ballroom. This would show their relationship in a more public and glamorous light, different from their usual secret rendezvous.
In some fanfictions, they could be studying together in the library but also stealing glances and little touches. It adds a cute and romantic aspect to their relationship while still being in the Hogwarts setting. For example, Ginny might help Harry with his Potions homework, and they end up sharing a sweet moment over a difficult potion recipe.
One interesting scenario could be them exploring hidden parts of Hogwarts together. They might find a secret room filled with old magic artifacts that have been long forgotten. This could lead to an adventure where they have to figure out how to use or protect these items from falling into the wrong hands.
It often starts with a growing attraction. Harry begins to notice Ginny in a new light, seeing her not just as Ron's sister but as a strong and independent witch. Ginny, on the other hand, has had a crush on Harry for a long time and now that they're dating, she shows him different parts of Hogwarts that he might not have known before.
One interesting scenario could be that they have a dinner by the lake at Hogwarts. Ginny might have prepared all of Harry's favorite foods, like treacle tart. They could be reminiscing about their adventures at Hogwarts while enjoying the meal.
Maybe they attend a pre - Hogwarts magic class together. Harry struggles a bit with some of the advanced spells being taught, and Daphne, though initially a bit aloof, decides to help him. This could start a relationship where they learn from each other, with Daphne learning about Harry's unique experiences outside the wizarding world and Harry getting a better understanding of the pure - blood society through Daphne.
One possible plotline could be the two of them trying to keep their relationship hidden from Ron, Ginny's brother. Since Ron is Harry's best friend, they might be worried about how he'd react. Another could be them sneaking around Hogwarts to have private moments together, like meeting in the Room of Requirement.
Well, in some fanfictions, a great scenario is when Harry chooses 'dare' and Ginny dares him to go into the Forbidden Forest at night without his wand. As for truth, Ginny might be asked the truth about whether she ever had a crush on one of Harry's friends. Also, Harry could be dared to imitate Professor Snape's voice during a truth or dare session.
Another scenario could be them working in the field of magical creature conservation. They might team up to save an endangered species. Harry's experience with magical creatures like Buckbeak and Ginny's love for all things magical could lead them to create a sanctuary or a breeding program for the creatures.
One interesting scenario could be Ginny getting ready for the Yule Ball with the help of her friends. They might be fussing over her dress, trying different hairstyles, and giving her advice on how to act around Harry at the ball.
In some fanfictions, there might be a scenario where Harry and Ginny get engaged during a dangerous adventure. They could be on a mission to defeat a new dark wizard, and in a moment of calm before the final battle, Harry realizes that he doesn't want to face anything else without Ginny by his side, so he proposes. Or perhaps it happens during a celebration at Hogwarts. After a big victory for the school, like winning the House Cup, Harry takes Ginny to the Astronomy Tower and asks her to marry him. There could also be a situation where Ginny is the one who takes the lead. She might plan a special date and then propose to Harry, showing her strong and independent character.
In some fanfictions, it could be that they are caught by Hermione and Ron, which leads to a lot of teasing and awkward moments. For example, Ron might make a big fuss about it while Hermione tries to be more diplomatic.
