Some students would probably cheer. There are always those who love a bit of drama and romance. But others, like the more traditional pure - blood families, might frown upon it. Fleur being part - Veela could add an extra layer of complexity. Some might see it as Harry getting involved with a 'dangerous' or 'exotic' element.
One possibility is that this kiss could be a spur - of - the - moment thing. Maybe they were caught up in the excitement of a victory in the Great Hall, like after a big Quidditch win or a successful defense against a dark arts attack. Then, they would have to deal with the consequences of their impulsive action, such as rumors spreading throughout Hogwarts.
Well, it could start with long - hidden feelings. Maybe Draco has secretly been attracted to Harry all along, and in a moment of courage in the Great Hall, he makes a move. This could lead to a series of events where they have to face the prejudice of their respective houses. The Gryffindors might be shocked that Harry is involved with Draco, and the Slytherins might think Draco is betraying them. Or perhaps it's a dream sequence that Harry has, and it makes him question his feelings towards Draco, leading to a slow - burn exploration of their relationship in the rest of the fanfiction.
Yes, there are likely some fanfictions with such a plot. You can try searching on popular fanfiction websites like Archive of Our Own (AO3). Just type in the relevant keywords, and you should be able to find some works that feature Harry and Draco kissing in the Great Hall. However, the availability may vary depending on the popularity of the concept within the fanfiction community.
One common theme is redemption. Draco, who was often seen as a bully in the original series, might be on a path of redemption, and the kiss in the Great Hall could be a sign of his new self. Another theme is the breaking of social norms. Since they were from different 'sides' in the wizarding world, their kiss defies those expectations. Also, the theme of hidden love is prevalent, as they might have been suppressing their feelings for a long time before that moment in the Great Hall.
Well, in many 'drarry' fanfictions where they kiss in the Great Hall, it's often a moment of intense emotion. It might be a culmination of a slow - burn relationship. For example, Draco could have been having a change of heart towards Harry over time, and in the Great Hall, with all its grandeur and the presence of their peers, they finally give in to their feelings. It's a very dramatic and exciting scenario that fans love to explore in fanfiction.
There's a fanfiction called 'A Moment of Magic'. In it, the kiss between Harry and Fleur is a result of a magical accident that leads to unexpected feelings. It has a very interesting plot that keeps you engaged throughout.
One common theme is the exploration of forbidden love. Since Harry and Fleur are from different backgrounds and there are various social and magical barriers, this adds an element of excitement and tension.
In a fanfiction, the three of them could be in the Great Hall for a sorting ceremony that goes wrong. A new student's magic is so powerful that it disrupts the normal process. Harry, Hermione, and Ron step in to calm things down. Hermione uses her vast knowledge of magic to try and control the situation, Ron's loyalty and bravery encourage the other students not to panic, and Harry's natural leadership helps them come up with a plan to contain the new student's magic until the teachers arrive.
Their characters could also be developed through shared experiences in the Great Hall. For instance, they might face a new kind of dark magic threat in the Hall. Through this, Harry could show his leadership and Ginny her loyalty and fierceness, and they would learn more about each other and themselves as they overcome the challenge.
