Why is it called "24 Hours of My Secretary's Wild Desires" if all the innuendos are car/driving related? When does the 24 hours of fucking happen it's been multiple days in the manga?? A better title would have been something like "Getting Hot and Heavy in the Fast Lane! My Sexy Secretary Wants to Rear-end Me With His Huge Dipstick?!" Still doesn't have anything to do with the plot but at least the bad car puns would be more relevant.
