Hmmm... Prime Minister dude, if you're going to have that attitude, don't show up at people's house. You're the fucking Prime Minister, have the decency to realize you're imposing on someone's hospitality, someone who was forced into your world by your country's impotence. So fuck you.
But, let's face it, the biggest problem is just lazy mangaka reusing old tropes. Every story MUST have a bloody tsundere, God forbid we use other interesting character types that aren't assholes to cover up their fucking insecurities.
Don't get me wrong, I'm all for gruff characters. But for fuck's sake, don't dress them up like hissy bitches and try to force them into the bloody story.
