I'm sure. Johnny's Manchurian and Nadia's Han. He likes her but after knowing she was pregnant with Kong's Wah baby, he said they'll just become brother and sister.
No, not Lok Ying Kwan either.
next: 1. Ha Ping's son 2. Power Chan's friend 3. Cheung Chung Chi's superior 4. Law Mong's friend 5. Lee Fung's son
Well, maybe I'm thinking of another character. Does Nadia have a cousin in the series. I remember him (Johnny) liked her before she met Kong Wah. I'm so confused!
Michael Tse? (#3 is the only series I can't think of).
No, Nadia did not have a cousin in HEA. Yes, Johnny did like her before she met Kong Wah, but they are not cousins. I think you're assuming that they are cousins because Johnny likes her from the start.
No, not Michael, but I think you may be on the right track.
hint: Michael is this person's friend too, along with one of the clues previously given.
