Oh, well okay... So, basically it starts as four years backwards. The present day.. For example, the present year is 2016, right? So, the story begins in the year of 2012. The next chapter is still in 2012, only six months ahead. So, January 2016, then skip to June 2016. So, basically I've moved backwards from moving four years ahead. I've gone four years back. You get it, or did I confused you even more? ;)
