The Royal Family took over Victoria Houghton's family business, now The Royal Inn, and although they provided her a top management position, they are, for the moment, placing her as personal assistant to Duke Charles - the one royal who thinks commitment is a dirty word and has dipped his wick in more women than he can count. On top of that, he has a history of sleeping with his personal assistants. But Victoria gives him a run for his money and puts him on the chase. He's suddenly far more interested in her than he expected and even once he gets her into his bed, he isn't ready to give her up so soon. But Victoria has a tendency to fall hard and she does with Charles. But she fears he'll never love her back.
Okay, so this might not have been so bad if Charles weren't who he was. The first problem I have here is the premise. The royal family actually wants to keep Victoria on as management because she's so talented, but they put her in a personal assistant role first to see if they can trust her. But they know that Charles sleeps with all his personal assistants and that he doesn't do commitment - so how is this furthering their interests? Charles goes through 1-2 personal assistants per month. That's not a smart move - would have been better to put her in another position somewhere else. Second problem I had here was that Charles was a slimeball who objectified women and figured every one of them would sleep with him eventually. Not to mention he brings it to the office where he's not only a Duke, but also the boss expecting women to sleep with him. So he's the poster boy for sexual harassment (and the royal family hasn't done anything about this?). He hits on anything with tits and despite Victoria telling him no, he keeps going. But eventually she finds it cute rather than annoying as she initially did.
Which is of course why she decides to sleep with him...well, she has a fight with her lying father and then decides to blow off stress by sleeping with him. He has a token moment of honor when he realizes she's emotionally stressed and a bit buzzed on alcohol, but what the hell, he sleeps with her. And then it's sex, sex, sex all day long at work. Professionalism goes out the window. Does this guy actually work? But Victoria maintains that all they have is sex and not even friendship, which Charles is surprised to find hurts him a bit. He's also astonished that he hasn't gotten bored and moved onto hotter women. But then Victoria admits she loves him and it's all over. Until his former playboy cousin shows him how happy he is in marriage and suddenly Charles is thinking how happy Victoria made him. So he goes to her house and drops the "love" bomb and she's so happy to marry him. There's absolutely no question of trust or the fact that he's never had a relationship last beyond a month (probably less than that) and IMHO he'll be cheating on her in a matter of weeks. I honestly do not see a good future for them...he'll be flirting at the office and ducking into hotel rooms with maids before too long. He didn't really learn the lesson about love and commitment, he just didn't want to lose the good thing he got.
