I picked this drama because I wanted to watch the main leads and to take a break from historical palace dramas.

I would say the chemistry of the main leads was good, though I did think the FL was a little on the heavier side for xiao long nu, I didn't think she was pretty either, but overall she grew on me, as time went by, I thought she was acceptable.
The ML was good, nothing negative to say about him.

It was a good break from historical palace dramas because the drama was all about the pugilist world. Nothing about palaces, emperors, scheming, wars, etc. Good to watch such dramas once in a while. I enjoyed it!
