I totally understand. There is nothing like a good romance.
I am currently seriously hooked on: Before we get married. - the chemistry between the leads is off the charts. I wait for this show every week and it hasn't disappointed me yet.
Other romances with great chemistry between leads...
Just between lovers - beautiful story, beautiful dialogue, will never forget it
Weightlifting Fairy Kim Bok Joo - this was so good and so fun.
HIStory3: Trapped - Bl at it's best. Great chemistry and acting.
Hope you can find something you'll love
