I think Tse Kwan Ho did a great job with playing Nick Yau because Nick's a person who has trouble showing his emotions therefore, he doesn't have much expression very often. But whenever he's with Michelle(Myolie's character) his true feelings come out and he can be himself. Those are my favorite parts of the series. I personally think Tse Kwan Ho looks pretty cute with his calm nature, cool personality and those spiffy glasses. He totally doesn't look 42 years old in this series.
