Can't you take a hint? Or do I need to spell it out for you?! No. I don't want to go on a date. I don't want your cheap chocolates. I don't want your proclamations of love. Can we get a hundred percent less of you around my general vicinity please? I mean, I'd lie and say it's not you? But it's definitely you at this point. I mean, who doesn't understand that no means no? The mentally incapable? The- Oh Kami-- you're an Otaku? A thousand percent less breathing my air please."
