Grace Chan finds a strand of long hair on Kevin Cheng's jacket. But, no, Cheng is not cheating on his wife of two years. That's actually the premise for a commercial featuring Hong Kong's golden couple.

And if that premise sounded familiar, it is because the campaign for the commercial was inspired by the popular K-drama, The World Of The Married. A remake of the hit BBC drama Doctor Foster, The World Of The Married centres on a woman who goes all out for revenge after she discovers her husband has been cheating.
