Soulmate - A Haechan Series

Soulmates. That word is already common in the world you live. In 3021, a lot of things have changed. The technology evolved a lot. Things the Men never imagined before are now possible, but together with that, came the war, the competition, the wanting to evolve more and more, and, with that, the world entered in collapse.
In order to solve that situation, the researchers created a national exam to select the most skillful young people of the countries to be the saviors of the nation. After many tests, each one harder than the other, the researchers found out that the young people would have a higher chance to survive if they got separated in couples, creating then, the Soulmates.
