It's clear everyone has a different idea of the concept "chemistry".
While I appreciate good kissing like everyone else, I don't think kisses or even sex are a guarantee of this so called chemistry to appear on screen. The circumstances leading to a hug, a touch, a kiss or sex are way more important to me. To use a simile, I think the mating dance is a lot more impactful than the mating itself.
In a movie or drama, it all boils down to the way scenes are shot and acted, to the music and the tension created BEFORE the deed, whatever that may be.
Keeping this in mind, and omitting the dramas you have seen and mentioned, I'd recommend:
Fated to Love You -(K-version)
Autumn Concerto
Pride - (Jdrama)
Nagareboshi
I Need Romance 1
*edit* sorry, I didn't realize this was a Korean thread only. I'll leave the recommendations though, if ever you should decide to cross the borders. ;)
