Comedies with literal LOL moments

Real life has made me a stress case and I'm looking medicate with laughter. I'm hoping to find some good comedy mixed with an engaging storyline that'll have me clamoring for the next episode (something with a storyline that stretches the entire series and not an episode-to-episode sitcom type setup.) I've tried a few that have funny moments, but are also super serious or dramatic which can end up stressing me out despite the humor and by then I'm already hooked (Angry Mom, Falling for Innocence, Kill Me Heal Me) so I'm trying to stick to fluffier stories. Romance is good, slapstick is fine, a sassy/quirky female lead is great, and I prefer stories with 20-30+ as the age range, but I'm open to whatever will make me chortle my stress away. Ones that I've seen that have done the trick recently include: Rooftop Prince, Ho Goo's Love, She was Pretty, History of a Salaryman, 20 Again, and Emergency Couple. What to watch next?

Thank you!!! From the descriptions it looks like I'll have some good laughs queued up!  Cherry Bunny, I have to bookmark that list!!!

No serious conflict, even the villains are lovable :)

*pokes head in*

I'd say The Greatest Love was a pretty good one. 

I recommend Haeundae Lovers -- do not let the "7" average rating dissuade you.  This is "light fluff," has romance and it's slapstick funny … and, it also has Kim Kang Woo in a comedic role and … check it out and you'll know.

I noticed you have Sorry, I Love You on your PTW list.  This is a sad story, but oh what a beautiful love story!  You may want to give this a try … a well-written script, fast paced and the acting is superb.  The love story between Moo Hyuk and Eun Chae is so moving you will probably forget about your own stress (hopefully).

First 8 episode of the history of salaryman...
the greatest love.

I agree. Switch Girl is one the best comedy drama I've watched,

also, Splash Splash Love!!! I can't stop laughing in each of the episodes. It's also just short and must watch.. It's like Rooftop Prince. You won't regret it :)

You'll love Kim Seulgi in there. I love her!! She's totally great comedy actress!

 If you did, you'll enjoy her in Oh My Ghostess too, it's a funny romcom with some mystery and fantasy.  

Check out Surplus Princess too. She's a supporting actress in there, and that drama's sooo funny! Actually most of the drama she's in, is funny. haha.
