Both series shares a cult like organization, leading people to believe in lies and covering crimes by involving past incidents that has nothing to do with an event happening in present. The lives of people closely tied with each other, it shares crimes of human beings.
People who are trying so hard to uncover truth & powerful people supporting the cults are creating obstacles.
