There are many of them, so I will write only some that I liked the most:
Attention Please - japanese comedy with wacky FL
I'm Not a Robot - it has some drama, but mostly it is great comedy and romance. Some scenes are very hillarious.
Mada Mada Koi wa Tsuzuku yo Doko Made mo - spin off of great japanese romcom.
My Love from the Star - korean romcom with alien ML, very funny
Shanai Marriage Honey - japanese romcom with many happy and funny moments and some skinship
Splash Splash LOVE - korean short romcom (2 eps)
Higuma - japanese comedy about one little bear
Love Like White Jade - chinese historical romcom/parody, very funny
Yuusha Yoshihiko to Maou no Shiro - japanese parody to RPG games
Yamada-kun to 7-nin no Majo - japanese school romcom with magic
Hello Harinezumi - japanese detective comedy. This is what I watch now, 1st episode was sometimes serious, but sometimes also so much hillarious that I was not able to stop laughing. :) Edit: first episode was fun, and even later there are some funny scenes, but it is not exactly best comedy drama.
