im okay with the reality that not all relationships start in decent or right manner..at first i thought this is a trash since I keep on reading bad reviews about it, but after finishing it, i can say its pretty good..it's realistic.. girls who are trying to suppress their feelings for each other, the other one who has psychological issues, the other one's totally confused/clueless because of the gender issue ,these factors drive the premise of cheating (without the intent of this person involved)....
people who are used to cute/innocent romance who hate the premise of cheating or otherwise will get pissed off at the drama that comes with this manga,that's pretty understandable...
but let's have to accept the fact that this scenario happens in some people lives no matter how much you dont want it..
NTR's not perfect, but if you are one of those who can accept the harsh realities of cheating,being deceived,not trusted and on, then give this a shot.
