JK's backstory

During the past few years, the world has become more and more violent - all 'peaceful' protests have stopped, most peace-promoting groups have resigned, and the future of the world is unclear. The people have now been separated into 5 groups - ice, fire, nature, cloud and thunder. These groups have sworn never to talk to anyone of the opposite group, and to avoid all contact or else be killed. Yet, fire boy Jungkook has a huge secret to keep - he's in love with the ice boy, Jimin.
