Forget about this shit. It's just another misogynist creation of some deranged mangaka who jerks off while he draws blonde girls who he likes to imagine as always smiling psychopaths and dark-haired girls whom he wants to imagine as overemotional victims of circumstances who (despite working in a job that requires them to have complete control over their emotions) conveniently are always showing a submissive or restless face when confronted with the blonde girl.
Go suck a dick, mangaka.
Since this is always so highly rated I really did wanted to give it a shot, but every character is terrible and I just get upset after every chapter hahah. Time to drop this one.
Though I kinda want to continue just to keep reading SotiCotos comments. He is a first class troll and it's much more entertaining than the actual manga.
