This IS TVB we are talking about. Not known to be accurate in history...
I think Kenneth is trying too hard to be a conniving Prince. The part where he put up a show and apologized to Natalie, I would have prefer him to have a solemn/unreadable expression when he had her in his arms. Instead, he's grinning madly like 'haha, you fell for it, success is MINE' expression. lol...
