Well, in this kind of fanfiction, the vampires from BTS might initially be intrigued by the kid reader. They could be protective, seeing the innocence in the kid. Maybe they would shield the kid from other dangerous vampires or supernatural threats in their world.
Well, the vampires of BTS might be initially intrigued by the kid reader who is a Daredevil fan. They could see the kid's courage, inspired by Daredevil, as something both endearing and a bit of a mystery. Maybe they would try to protect the kid from the darker aspects of their vampire world, while also being fascinated by the kid's knowledge of Daredevil.
The BTS vampires might interact with the kid reader in a very gentle way. They could offer the kid small gifts, like a pretty flower they found in the forest at night (since they can move around at night).
It depends on the individual personalities of the BTS vampires in the fanfiction. One vampire might be really excited to hear about Daredevil and engage in long conversations with the kid about the character's abilities and storylines. Another might be more aloof but still secretly impressed by the kid's passion. And yet another could see it as an opportunity to teach the kid some real - life skills that are different from what Daredevil does, using their own vampiric knowledge and powers.
One possible moral could be about the importance of kindness. If the kid in the story shows kindness to the lion kid, it might teach that being good to others, regardless of their appearance or power, can lead to positive outcomes.
I'm not sure of the specific full story without more context. It could be a case of a bully targeting a vulnerable blind child, which is extremely cruel. There might be underlying reasons like the first kid having some behavioural problems or being influenced by a bad environment.
