A unique feature is the clash of two very different universes. Naruto's world of ninjas and chakra is completely different from Asuka's mecha - piloting world in Evangelion. This contrast makes for really interesting storylines.
Stray Kids, on the other hand, would also be very concerned. Bang Chan, as the leader, would take charge. He might start asking questions to figure out what exactly happened. Felix could be bringing water or something to make Y/N feel better. Lee Know would be standing guard, making sure no further harm comes to Y/N while they are in a vulnerable state.
There is also 'Naruto and Asuka: A New Adventure'. It delves into how Naruto's ninja skills and Asuka's piloting abilities combine when they face a common enemy. It's really exciting to see how their two worlds collide in the fic.
Y/N should have their own goals and dreams. If they're interested in becoming an Auror, that can shape their actions and decisions. Their reactions to Draco should be based on their personality. If they're a shy person, they might be more hesitant around him. And make sure their dialogue is natural. Don't make them say things that are out of character just to move the plot along. For instance, if Y/N is a studious type, they're more likely to talk about books or spells when interacting with Draco.
They might immediately stop the concert. The members would be really worried. For example, Jin could rush over to where Y N is with a concerned look on his face. He might ask the medical staff what's wrong and offer words of comfort.
One popular 'asuka y shinji fanfic' could be those that explore their complex relationship in a post - apocalyptic setting. It adds an extra layer of tension and forces them to rely on each other more.

It could also be related to the internal politics within the entertainment industry in the fanfiction. There might be some higher - ups who don't like Y/N's presence around BTS and Stray Kids. So, they arrange some difficult situations for Y/N which end up in Y/N getting hurt. For instance, they might give Y/N impossible tasks to perform and when Y/N fails, there are severe consequences that lead to their harm.
