There's probably more lol!!
Kiss Me: romance, comedy. Itazura na Kiss remake. Same leads as Full House, great chemistry. 
Full House: romance, comedy. Few plotholes. Great chemistry between leads. Some gorgeous settings. 
Ugly Duckling Series: teen, romance. Individual stories were cute and each installment is 9 eps or less

I haven't seen very many Thai dramas yet so I'll be lurking for ideas as well! =]
Hi Kat! I could give offer some recommendations depending on your preferred genre ^_^
Romance is definitely my preferred [slap/kiss included; they're my favorite] but I'm open to anything as long as the storyline holds my attention. Biggest issue for me is finding somewhere to watch with English subs. =]
@Kat Yup, that can be quite a problem, below are some legit sites XDD

GMMTV has a YT account and they sub some of their series
Jasmin Lakorns blog gives updates on where Lakorn viewer can either download or stream watch most Eng subbed Lakorns and completed shows are also grouped according the genres. So you can just scroll through each trope^^
And there's always Viki XDD

I highly recommend - Sapai Jao 2015, it's pretty straightforward, hilarious and romance of course (Viki)
- Padiwarada - action, romance and drama (Also on Viki, but the last 2 eps are still being subbed)
- Sawan Biang - heavy slap/kiss (Jasmin Lakorn)
- Leh Ratree 2015 - It's a remake of the 2005 or version. It's pretty interesting - mild slap/kiss, romance and comedy (Viki and Jasmin Lakorn)
Sapai Jao is one of the ones on my Viki list that I just haven't gotten around to yet. I hear a lot of good things about Leh Ratree too. I'll have to bump both of those up on my PTW list. Thanks for the sites too!
