I've watched all three versions of this drama and this is my favourite. I started with the 2016 version, then moved on to the 2008 one, and then finally watched the 1999 series. This has probably one of the darkest undertones of the three versions.

One of the darkest elements introduced in this series is The Hiruwat family raising Bpee with the intention to groom her into a concubine for Wat Hirunwat, the father of the family. While this revelation is horrifying, it adds to the story by highlighting Bpee's gratitude. I think this version explains the FL's gratitude and loyalty towards the Hiruwat family the best out of all the versions released. We see that she had once struggled to accept Viyada and her family and is not blindly thankful. She's aware of their evil intent but she's too thankful towards them to do anything. Unlike alternate versions, where she was essentially a slave, she was able to go to school and work. She is aware that without the Hiruwat family's support, she would have been reduced to nothing. Not to mention, the family isn't entirely bad, she did have an ally with Pa, Viyada's sister. Pa is one of Bphee's greatest support in the series.

Another I really liked is, Mothai is much smarter in the version. He didn't blindly believe in Viyada and her lies until the very end. He recognized that Vyada wasn't as sweet and kind as he thought and was smart enough to question her. Also, he was touchy with Bpee but it was never as aggressive as the 2008 version. The 2008 version sometimes got too aggressive in that department.
