It's weird/amusing that with each passing chapter, the title of the manga becomes less and less relevant to the overall plot.
It's like the mangaka intended this manga to be a parody of ecchi manga with a main girl who despite being willing to do anything sexual is only used to do mundane stuff.
Now it's turned into a workplace rom-com about a waitress crushing on her older boss while the café they work at struggles to stay afloat.
