Love? Ah, really, so bold! [souji knows that there is nothing short of million misunderstandings here.

after all, he knows mitsuhide is not a lady. and he knows that romance novels are unrealistic as hell; they on the tier with shounen and shoujo manga for ridiculousness.

but of course, instead of actually taking any strides to clear things up, he plays along with it. because he's a baby shitlord, and it's really funny. he really hopes he can get the aftermath of this... or reveal it in some comedic way himself.]

Did you ever consider that maybe Mitsuhide-san is a shy type who wouldn't want everyone to know about your forward confessions?
