Rom-Com Royalty

The name of "Rom Com King" and "Queen" gets thrown around frequently with drama lingo. Park Seo Joon and Park Min Young have even earned the title (officially? unofficially?) themselves. Many artists are funny, but how do they do when it comes to making a good laugh swoon-worthy like Kim Seon Ho in Hometown Cha-Cha-Cha? Feel free to add artists with one hit wonders, even those who aren't  the main love interest in the show.  Any country is also welcome. What do ya'll think?
