They might start by sharing their favorite BTS songs and music videos. The vampire could use his enhanced senses to experience the music in a unique way, which the girl would find fascinating.
The vampire and the human girl could interact in various ways. For example, they could attend BTS fan events together. The vampire, with his supernatural abilities, might protect the girl from the chaos of the crowd. And during their time together, they would discuss their different perspectives on BTS. The girl might talk about how BTS' lyrics inspire her, while the vampire could be more interested in the way their music and performances seem to have a certain magic that even he, as a vampire, can't fully understand. As their relationship develops, they would also have to deal with the differences between them, like the vampire's nocturnal habits and the girl's normal human schedule.
The plot could be that the vampire, who is secretly a BTS fan, meets a human girl at a BTS concert. He is drawn to her because of her pure love for BTS. They start to bond over their shared interest in BTS, but he has to hide his true vampire nature from her to avoid scaring her away.
One common theme is the discovery of new friendships. The girl often starts as a regular fan and then forms deep friendships with the members. For example, she might bond over shared interests like music or art.
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).
First, think about the characters. Decide which BTS member will be the vampire. Consider their personality traits and how they might be affected by being a vampire. For the human, create a relatable character. Then, plot out the story. You could start with an interesting encounter between the two, like the human getting lost and finding the vampire's hideout.
The relationship can start with a chance encounter. For instance, the human boy might be in a dangerous situation, like being lost in a dark alley where the vampire girl happens to be. She saves him, and from there, his curiosity about her grows.
One possible plotline could be the girl initially being scared of the hybrid BTS members but then gradually learning about their kind nature. For example, she might first encounter them in a mysterious setting like an abandoned building. As she gets to know them, she discovers their unique abilities and forms deep friendships with them.
Obviously, the human girl is a main character. She could be an ordinary girl with a big heart. And then, the BTS members as hybrids are also main characters. Each member might have their own distinct hybrid traits. For example, one could be a wolf - hybrid with enhanced strength and a protective nature.
There's also 'Unexpected Meeting'. In this fanfiction, the human girl reader meets BTS in a very unexpected situation during a concert. The way their interactions develop is really interesting and full of surprises.
At first, the elves might be a bit cautious in their interaction. But as they get to know the girl better, they become more open. They could teach her elven languages and magic spells. In return, the girl might introduce some human ideas and games to the elves. This exchange of cultures makes their relationship more interesting and complex.
I recommend "Vampire Farewell". This is a fantasy-mystery fantasy novel that tells the love story between a half-vampire boy and a girl. In this world, the existence of half-vampires was very common. The female protagonist was a girl with half-vampire blood. She had feelings for a half-vampire boy. They were full of mystery and confusion. The plot of this novel is very fascinating, full of fantasy and romantic atmosphere. I believe you will love it. I hope you like this fairy's recommendation. Muah ~😗
