Here we have that old story, where the guy is cold and the girl is a fool. When he says "At work, I am your superior, but in this area, you're the master" (cp 12) the first thing that came into my head was bdsm.
I wished that from that sentence, she would take control. But that doesn't happen, I went to chap 22 and that's where I stopped.
