My first Thai drama was Tra Barb See Chompoo and I kinda liked it even though the ML got on my nerves later on.
After that I discovered some really good Thai dramas, among them Hua Jai Sila, Sawan Biang, Waen Dok Mai, Kleun Cheewit, Leh Nangfah, Leh Ratree and Roy Leh Sanae Rai.
What I personally really liked was that they are sometimes really aggressive and also show a lot of unhealthy relationships. Sometimes I don´t want a cute bubbly love story. Sometimes I want to watch an unhealthy relationship, where the Female Lead is abused by the Male Lead (Yeah, I know that sounds weird, but I just like them xD)
And I like Forced Kisses, Kabedons etc. and lakorns are filled with that. The other dramas don´t really do that stuff a lot, so I just silently watch my Thai Dramas °^°
