Decent guess. It is about a thief who was raised by the mob in Hong Kong and manages to piss off the next leader (his adopted brother) and a bunch of other triads. He ends up getting recruited by The Director to work for her alongside his ex-girlfriend/not-actually-sister and her new fiancée. In Canada. Wackiness and choreographed fights ensue.

Bridgerton Series:
About the family Bridgerton through several generations of marriage and children. And also, vampire slaying. (Yeah, that last bit I made up.)
