I thinks the choice to move the story backward is kinda brilliant, it keep to mystery going and not really "depressing as fuck" anymore and for this we know them not because how they end but how they live. This become bitter sweet now maybe because we know the ending before it unfold. It just life people choice different path and I not saying which one is better, it just different.
Though their life I think I have learned that maybe life is that fuck up and it will bite you if you chicken out, so I think I will just take any chances when they come and maybe things will work out okay. Not saying that the choices that I make will always right but at least I make it by your own will and I can regret or grateful with it.
The first 3 chapters are hard to get though but I hooked now. Can wait to see how it unfolds.
