Different Nobodies | kth x jjk

Taehyung is a boy who was orphaned at a young age, mother died and father no where to be seen
Jungguk had lived all his life in a lab, where they would run tests and experiments on him, waiting for the day he could be sold of to the government for even more torture.
Namjoon, the cyborg. He doesn't remember much but dont let that fool you, he has the brains of Einstein and the power of superman, having lost his arm and legs at a terrible accident turning them into electronic limbs.
Jin is someone who had studied all his life, mother pushing him to do his best, but after a plane crash that left him stranded in the who knows where forest where he would spend almost the entire rest of his life at.
Yoongi, the hopeless boy. He has no other family apart from a very kind old woman who accepted him in her house. Now he barely goes to school and commits so many crimes ever since that kind old woman left the Earth.
Hoseok, oh poor hoseok. A cashier who's known for the smiles and the bar tender who's known as the best kisser. This boy has spent his entire life in the poor living with his grandfather.
And last but not least, Jimin. No one knows who Jimin is, but more precisely, what he is. You could never encounter him unless you were brave enough to enter the deep ends of that tunnel. The tunnel hes spent who knows how much time in.
These seven unfortunate cases all have something in common, they're all unfortunate. What will happen once something so big, as in destroy-the-entire-humane-race-and-possibly-the-world big calls upon fate to bring them together?

Switch for all ships,
And very slow updates bc I'm very bad at coming up with ideas and actually writing them down.
