Honestly was expecting lil hints along the way about what happen back then... instead all we get are the same flashback images since the start.
I have absolutely no clue of what might had happen but what ik is that i cant imagine being something as serious as what this gap between them has become. By simply postponing continuously it had become constantly harder to come out and say it. To the point that the desire to spare the other from being hurt is edging the limits of thrust. Both are equally guilty.
I hate hardcore drama and absurd amounts of misunderstandings tha fill most pages of the standard romances of lately, so this is a breathe of fresh air, no doubt. But even so, im getting really frustrated of how things are steadily getting complicated in a worrisome snow ball effect.
