Leh Ratree (2015)  http://mydramalist.com/13397-leh-ratree. This is the version with Sean Jindachote and Esther Supreeleela. I just finished it and it was really good. This was my first Thai drama that skirted around the whole slap/kiss genre. Honestly the plot was insane but once I started it I had to finish it, because I had to know how it would turn out. 

Oh awesome, I will check it out. I added it to my list, also Cubic which I haven't seen. I just found Thai shows in like January and there are so many! I am really liking them so far ^^

I'll list a few that I think meet the strong female lead criteria. This is going a bit from memory so it might not entirely be accurate:

Koo Za Rot Zab - Male lead is a womanizer. Female lead runs a small business to help her community. They end up in a 'forced' marriage each doing it for their own reasons/benefit. She's a hard worker, capable and smart - she's a business woman basically. His father and sister love her (in a family sense). It's a romantic comedy. 

Ruk Sutrit - Spoiled rich kid failing at school. Tutor is hired to turn him around. Eventually he falls for her, the tutor.

Kluen Cheewit is a little more 'violent'. She killed his fiance and he thinks she has escaped justice. She's an actress with a career. Hate turns to love eventually.
