Just to name a few, I like Raymond Lam and Myolie Wu in Survivor's Law, Raymond Lam and Michelle Yip in Eternal Happiness, Kevin Cheng and Niki Chow in Hard Fate. I would like to see Bosco Wong and Nancy Wu, Ron Ng and Nancy Wu pair up together again.
i say ron ng and leila tong have the best chemistry in twins of brothers. I also liked ron ng's chemistry with ella koon in rdov, ron ng's chemsitry with shirley yeung in find the light and raymond's chemistry with leila in the last breakthrough.
Ps. Joe ma and kenix also had a good chemistry in vigilante force
