Jin:
You met Jin in a language learning program. He wanted to be better in English and you wanted to be better in Korean. Having to live 90 days with him, you both had to really adjust to the culture shock. By the 50th or so day you both were comfortable with each other. Even after the 90 days, you both remained in touch and soon moved back in with each other.
Suga:
You met Yoongi in fly away trip at your job. You and him were co workers but never talked to each other. Being the only two specialists of your jobs, you both had to work together which also meant live together. It wasn't too bad, just getting adjusted to.
Jungkook:
You met Jungkook while he was in your home state. It was weird because you would have thought a celebrity like him would have gone somewhere high class or even well known. Nope. He actually got separated from literally everyone. His phone died and his stuff was with the group. He just so happened to knock on your door. You instantly recognize him and with his English skills you were able to get an understanding of what happened and let him stay in your guest room. That next morning, you made him breakfast and he was able to call the others. He thanks you and writes a personal letter to you and pays you back for the money you spent, buying him dinner since you ate your leftovers and with that he was gone but somehow, just by faith you both managed to get back in touch. You both haven't lost contact since.
