Seriously, I wished that more manga authors would get more awareness about having people touching members of the opposite sex. In an environment as depicted in this manga, I don't think touching someone else's maid or female companion would just be laughed off. Never mind this setting, even if someone laid hands on my colleague without her consent, there would be trouble. Grins and nervous laughter would be the last things to be shown.
Hell, even women on their own wouldn't tolerate that shit. Don't believe me? If you're a dude, go put your hands on the shoulder of any female stranger, see where it gets you.
I get that this is a work of fiction, and ultimately the scenes depicted reflects the innocence of its intended audience, but something about this just rubs me the wrong way.
