"The dude is more concerned about getting a chance to relax and doesn't immediately want to fuck a girl he doesn't know just because she's hot, therefore he must be an asexual and the only people it can only be marked to incels."
Some people aren't as horny as you, my dude, and manga in Japan has a way wider audience than it does in the west where only turbonerds read it.
I don't totally disagree with what you're saying though, it's weird that the black company thing is getting super popular out of nowhere (probably all the mangaka who heard about it growing up but ended up drawing manga instead of joining the work force so they don't know what changed) and it's hard to believe that someone who fucks dudes in their heads as a career would get all blushy over imaginary hand-holding. Maybe if it was a "this is her first job" situation it'd make more sense, but page two of chapter one seems to imply that she's been doing this for a while, so I dunno what's up with that.
