I didn't really like this one until I watched it a second time and realized that despite all the frustration, it is a very well-done drama.
STORY: Absolutely frustrating. I wanted to scream at every single character almost every time one of them opened their mouths. However, the plot was well-paced and was not over or underdone. Such a dramatic plot is very easy to go overboard with, but the writers knew exactly which buttons to press to get our emotions riled up, and then left the story alone. I personally was a little disappointed with the conclusion because it felt foreign compared to the rest of the drama, but it wrapped things up fairly well.
For the couplings, I was super invested in Piak and Chaiyan and Sathit and Jee, but I felt that Dao and Jade were superfluous. However, I rarely get invested in side couples, so it was mostly me.
ACTING/CAST: Yaya completely blew me away in this drama. I've seen almost all of her lakorns, and she's always been good, but WOW.  Jee was a very complex character, and Yaya pulled it off like nobody's business. Yaya created a Jee who seems tough and cruel on the outside, but she's really a caring, vulnerable person on the inside who had to learn to defend herself.
Mark did a good job as well. I still felt didn't quite reconcile the different facets of Sathit's personality into one without appearing to have MPD. Sathit is obsessive, but he's also cute at times and a real gentleman. Mark did an adequate job, but in the last episode, I wondered if I was watching Sathit or some other character I didn't know about.
Louis was a sass king, as usual. I especially liked how he showed that Chaiyan wanted to blame Piak completely for their troubled marriage, but that Chaiyan was also to blame in part. Also, when Louis cried, it was so real... he's not the hero with perfect makeup making tears fall, but he's the real person crying, screwing up his face and trying to stop the tears from coming.
I love Toey, but her Piak made me want to throw my phone at the wall, which was kinda the whole point of her character. Well done, Toey.
MUSIC: Lovely. It varies, which is something they usually struggle with in dramas. The music was passionate and dramatic, but also cute and loving. Pretty sure the same people who wrote the msuic for Piang Chai Kon Nee Mai Chai Poo Wised wrote the music for this one.
REWATCH VALUE: It took me a year, but I rewatched this one all the way through. I thought it was actually better the second time through, because I already had the story, so I could pay more attention to the actual characters and such.
Overall, this drama is for those who love drama and angst. If you don't look elsewhere. It's frustrating and will make you ugly cry, but the drama really is very touching and will give you hope that true love might actually exist.
