My definition of a bad couple is two people who have no romantic onscreen chemistry with each other at all. That being said, I nominate Chuno’s Un Nyun (Lee Da Hae) and Tae Ha (Oh Ji Ho). I’m not going to start a fire by saying anything bad about either Lee Da Hae or Oh Ji Ho, but I will say that these two just had no chemistry whatsoever. I also couldn’t really ship them, since it’s not like they truly loved each other. Poor, poor Dae Gil.
