Uh... little dark, isn't it? I think Miss C. was just date-raped by this falsifying philanderer. 
Dark yes. But he was a random stranger just as she was expecting. A blind date. He treated her well and did probably what she had hoped for in a blind date, then he left.
So yes, you can see it as dark, or you can see it as the perfect date.
She even said this was the happiest she'd been in awhile. And he ends by saying "at least you had a good time!"
