Kim Hee Ae made it hard to believe that she is in her forties with her toned figure and timeless beauty, making fans unable to feel a 19-year age gap between her and Yoo Ah In, especially with some steamy skinship like one would expect from a drama called 'love affair'.  

'Love Affair' will premiere on the 17th at 9:50 PM KST!
