His bandmates would likely be involved. They might be the ones who first notice Jungkook's headache. For instance, Jin could be the mother - hen figure, trying to get Jungkook to rest and making him some herbal tea to soothe the pain. J - Hope could be the positive energy, trying to cheer him up and make him forget about the headache through his jokes and antics.
One thing that might make it different is the theme of 'the taste of love'. It could be that the author approaches the concept of love in a more unique way compared to other fanfics. For example, it might focus on a more mature or complex understanding of love rather than just the typical puppy - love scenarios.
Jungkook's character can be developed by showing his internal struggle as a vampire. His anger could be a mask for his fear of not being accepted. For example, when he gets angry at a human in the fanfic for being too nosy about his vampire life, it could actually be because he's afraid of what would happen if his secret got out completely. This shows his vulnerability and adds depth to his character.
The main distinction of porn with a story genre from regular porn is the presence of a coherent narrative. Regular porn often jumps straight to the sexual action, while the story genre tries to add some kind of story framework around it. But in the end, both are adult-oriented and feature explicit sexual content.
Well, it's hard to say for sure. The concept of 'porn-like' is quite subjective. Some might consider certain novels with excessive sexual descriptions as such, but it depends on individual perspectives and cultural standards.
In many places, 18+ porn comics are considered illegal. This is because they can have a negative impact on society and violate moral and legal standards.
