Adventure for a Cure ［a short Tales of/BTS crossover fanfiction］

1/1

It is something like ass-o'clock in the morning when someone decides to bang their hand on the front door.

Yoongi isn't the kind of person who'd sleep in peace, then wake up in the morning to sing happily, no. But Jimin, one of his dearest friends, is really sick so he has to get to his feet to open that damn door.

Almost everyone is sick within their village, so they have to wear masks to prevent the sickness from spreading even more, and from infecting those who are still healthy; like Yoongi, or Jungkook, or Taehyung.

Its source is unknown, but it's like cancer: nearly impossible to recover from it, and deadly.

When he hears the younger cough, he is scared he'd be awake, but he decides not to check on him and goes immediately to the entrance of their tiny house.

"Hey Yoongi-hyung." A brunette boy smiles at him and the sun behind him is melting his eyes.

"Hey, Jungkook-ah." He doesn't smile back, and yawns instead. "What are you doing here, this early?"

Jungkook grins. "I have taken a decision!" Yoongi blinks but says nothing, so the younger continues. "We're going on a great adventure through the entire world, all together! We will be heroes! And you're coming with us," he says and takes his hands in his as he smiles softly this time.

But Yoongi is confused. "You... what?" He squints his eyes then pulls on his hands, forcing him to come inside to prevent the sun from killing his eyes. Why would he do something like that? He's definitively out of his mind. "Wait, Jungkook. You don't know what's gonna happen. We don't know anything about what might happen outside! Do you know how many people died because they were unconscious like you?"

"Do you?" Jungkook asks back, but Yoongi remains silent. "What else is there to do anyway? Stay in this village to rot?? And be sick to death??? No way. You know I'd rather live with passion, right? Yeah, I'd rather die outside than here. No offense to anyone living here, but that's what I think. Besides, we all know most of us is sick and some even died, so we need to find something to help, and I'm not changing my mind just because you're scared."

When they all used to go to school, they have learned how to fight, how to use spells, how the outside world could be, what kind of monsters could be out there... Yoongi is the oldest, so he has to watch over the three younger boys, like they were his little brothers. However, Jungkook is always bored of doing the same things over and over again, and Taehyung likes playing with fire, so both of them would leave the village just to have fun and see for themselves how it is. Most of the time, Jimin would be scared for them and Yoongi has to look for them, and, most of the time, they would come back with wounds. If just around the village is dangerous like that, he can't imagine how the rest of the world could be, and he doesn't feel like exploring and risking his life for it.

This time, it's different. Their own village is a danger itself, and they don't know why. It's like some kind of evil group is trying to destroying them by spreading a poison all over their territory.

The mayor sent soldiers to find a cure, or something, but they never returned.

Some people died within a week, and the illness started about two weeks ago; Jimin's appeared about a few days ago. Yoongi doesn't feel like leaving him all by himself.

The raven-haired male is about to say something when he hears coughing coming from Jimin's bedroom. He sighs again and leaves the younger to take care of the shorter male by bringing him a glass of water.

As Jungkook is watching him walk away, he crosses his arms and startles when another boy makes his way inside without knocking. "When will you finally admit that you and Yoongi are boyfriends?"
