I thought that the ML was pretty one dimensional. He started off as a rude and grumpy workaholic. Then his loins took over his mind and all he thought about was boinking her. When she didn't want to jump in the rack with him, he was all mad at her for "seducing" him. Get real, dude, and put your big boy pants on.
Somehow, I feel this girl is so unprofessional. I mean, what's she's doing with her employer honestly. It's okay if they take time to fall in love. Isn't he busy? Well...he's not busy enough to somehow fall for his daughter's governess
