The writting is confusing: it has very touching and well written scenes, but broken by the fan service and weird tension breakers. I don't like the main character Eco, but I love Kai.  Repetitive, dialogues that feel unnatural and forced. The main plot is lost by the constant interruptions of Kai and Eco relationship. I'm still enjoying it for now, but the tone and the writting is getting more confusing and unclear the more we read it.
