Doesn't bother him in the slightest. He'd take you over a dreary partner any day of the week. Discloses your closed-off behavior to be an invitation to challenge you, that's how you meet. Whether you are a demon slayer or not Inosuke's determined to get a reaction out of you.
When you are acting "strange" he'll tell you, but don't take it to heart as he means no harm. Inosuke's rather simple-minded, yelling inconsiderate things like, "Hey why are you so quiet! Talk more!" Without realizing your justification for being distant in the first place. Your loner personality irks him to a whole other level.
Would not tolerate any sort of disrespect coming your way. This loudmouthed teen won't bother biting his tongue. Although not understanding you well himself there's no chance anyone else will poke fun at you for it.
"Why does it matter? Agh, don't cry damnit! I like you, who cares about those guy's opinions anyway?!" He shouts, taking hold of your wet cheeks in his hands, gazing at you with determined eyes.
