prologue

"Happy birthday, Kook!"

Jimin smiles as he ruffles the younger's hair, making the boy huffs out in anger because he is not a freaking child anymore, for fuck's sake.

But Jungkook doesn't say anything. A part of his reason is Yoongi the vampire--which unfortunately is Jimin's boyfriend--who stares at him to shut his mouth.

So, Jungkook just clicks his tongue and let Jimin ruffles his hair.

"Spare the little boy's life, Jimin," comes the other voice. A soft smile appears on Seokjin's face as he puts down a box. "It's your cake, Kook. Let's eat it well, okay?"

Unlike Jimin who's fully a human or Yoongi who's a half-vampire, Seokjin is the most pleasant creature to have around. He is a matchmaker, the cupid, whatever you want to call him.

(He is actually a merman, but he loves human so he decides to visit sometimes.

Except it's not sometimes, but everyday.

He also loves to matchmake people, that's why.

Seokjin practically lives on land, if not for the fact that he sleeps in the ocean.)

Seokjin has been soft and understanding. It just gets too annoying when he gushes over cute couples that he helped, but that's it.

However, Jimin and Yoongi is not that hateful either. Their company is what makes Jungkook feels complete, after all.

Yoongi sits on his sofa, snapping Jungkook out of his thought when he says, "So, who's the first one you'll fuck?"

Jimin snaps his head so fast to Yoongi to the extent Jungkook could literally hear it snap. Seokjin chokes on his own saliva and screams.

"Yoongi! Watch your mouth!" Seokjin shouts.

Jimin covers Jungkook's ears and literally snuggles him. "Oh my poor child, pretend you didn't hear that, Kook."

Yoongi scoffs and stands up when Jimin says that. He grabs Jimin's collar and brings Jimin back to his lap, hugging him from behind.

"What? It's true, though," Yoongi says while he kisses Jimin's neck. "Jungkook is becoming an adult. That means he can't just absorb our energy anymore. He needs to fuck to get it, now."

Seokjin lets out a heavy sigh. "I know it's true. I just ... hope he doesn't experience that. Ever."

Jungkook just scoffs. "I do know, too, hyung. I know enough more than Jimin knows. I am an incubus, after all. I have to know those things."

He ignores the dramatic screaming of Jimin which says something like, "excuse you, kid, I know more than you! You do not disrespect your hyung that way!"

Yoongi smirks at his remark. "Then, who's the one that keeps asking 'what is this feeling?' and keeps whimpering when I first fuck--"

"Min Yoongi! Language, please!"

"Fine. When I first pleasure Jimin. There."

Yoongi bites Jimin's neck softly, not enough to make it bleed, but enough to make Jimin whimper.

"Hyung, please! Are you into exhibitionism because I surely am not into voyeurism, so you should find other people to watch you guys."

Jungkook also ignores the questioning expression of Jimin, asking for the meaning of exhibitionism and voyeurism.

The youngest sighs and gets lost in his own thought.

Apparently, today is Jungkook's birthday.

And he hates his birthday's celebration.

Jungkook is an incubus. A half of it, to be exact. He doesn't know the details since his father didn't tell him anything and his mother is dead, but he knows enough that Mr. Jeon loves Mrs. Jeon when he shouldn't love her.

And that's why Jungkook is born a half.

It is rare, indeed. Jungkook himself doesn't know it is possible.

As a half incubus, Jungkook lives like a human. He needs to eat, drink, and any other human activities.

Here is the twist. Once he is an adult--which is twenty--he needs to gain energy from other people. From pleasuring them sexually.

He knows them from his father, before he left him alone on earth.

Jungkook sighs. How can he engage a sexual activity when he himself is shy? How can he seduce women when he can't even watch porn without blushing?

(Yes, he acts tough, but the reality is different. He really is just an extremely shy boy in real life.)

Noticing his worries, Seokjin just smiles and puts a hand on the younger's shoulder.

"Don't think about it right now," he says. "Today is your birthday's celebration, so just cheer up! Let's think about those things later."

Jungkook nods. However, his guts tell him something is going to happen if he doesn't prepare himself.

And indeed something big will happen.
