Yes!, my guess is right. The song Mork sing is "Blame it on the star" by Bird Thongchai (released in 2002). The original song is here: https://www.youtube.com/watch?v=UqFKzVUyz2c
Since you speak Thai you may be able to help mewhats the significance of Mork or Mhok? Ive seen others use these…
According to the the royal Thai general system of transcription by the Royal Society of Thailand, the word "หมอก" should be transcribed as "Mok". Looks like GMMTV staff transcribed it letter by letter but just swapping the position of ห (h) and ม(m)... that's weird (at least to me)...
It ended beautifully.... Ah... I'm so glad to watch this series... will miss comment section... really happy to know there are many people adore this series like I do.
