Hi so I’ve recently become intrested in Thailand culture. I want learn Thai so I can visit the country one day. So I only know of BL for Thai dramas lol there seem to be a lot of them. Anyway I really would love to know if there are any original Thai dramas that Aren’t a remake of another drama l. Such as a Korean or Japanese drama. 

I hope you don't avoid remakes because some of the best are Thai. On many they do a great job infusing cultural flavor and adapt the stories to feel more original imho. Full House Thai and Kiss Me (Thai Itazura na Kiss) are great remakes. Aom and Mike have amazing chemistry.

Otherwise a few suggestions of Lakorns to get you started:

Kleun Cheewit

Mussaya

Muean Khon La Fark Fah 

Wannueng Jaa Pben Superstar

Neung Nai Suang 

Sao Chai Hi-Tech

There are also a lot of series Lakorns like U-prince and Ugly Duckling with different stories that are related to each other.

Try Ugly Duckling Series! My favourite is Perfect Match but the other stories are not bad too! (:
