In the fanfiction, Jungkook could be initially a bit panicked as he's not used to taking care of a sick baby. But then he quickly pulls himself together. He calls his mom or someone experienced for advice. He follows their tips religiously. He stays by the baby's side all the time, only leaving to get things the baby needs like medicine or warm water.
One possible plot could be that fans at the airport notice Jungkook looking unwell. They might be worried and try to get help for him. Some could offer him water or medicine if they have any. The story could then focus on how the other BTS members react when they find out. Maybe they cut short their activities at the airport to take care of him.
One more theme could be about the power of love in helping him get better. Whether it's the love from his family, members of BTS, or his fans. In these fanfics, love is sometimes depicted as a powerful force that can speed up his recovery and give him the mental strength to deal with the illness.
Well, the plot could be about Jungkook showing his kind heart. He might be really gentle with the sick baby. Maybe he sings softly to the baby to make it feel better. He could also be cooking some warm and easy - to - digest food for the baby. And throughout the story, the baby might start to get healthier because of Jungkook's care.
Fans in the fanfic would likely be very worried. They might form a sort of 'guard' around him, making sure no one disturbs him while he's not feeling well. Some might try to communicate with the BTS management to ensure he gets proper medical attention.
You can start by looking on fanfic platforms like Archive of Our Own (AO3). There are a lot of talented writers on there who create BTS - related fanfics, including ones about Jungkook being sick. Another place could be Wattpad, which also has a large collection of fan - created stories.
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.
On the other hand, some fanfics might create a distorted perception if they go too far with the 'hurt' concept. But overall, most fanfics that involve Jungkook getting hurt aim to show his growth, his relationships, and his ability to persevere in tough times. They can add more layers to the way fans view his character, making him more than just a member of BTS but a complex individual with his own struggles and triumphs.
