So I'm going, being honest, he and state that I AM A NERD of Dramas, and I blame my sister-in-law for this, but I was a nerd/geek/dork growing up. So I'm trying to see if any Thai dramas have a male lead who is geeky/nerdy/dorky.

So far, from what I have seen in lakorns, male leads are either jackasses or strong men.

in the gifted, there's Wave that is a IT geek, in notification the series there are all the main characters that are anime fans, in blacklist there's another IT geek, called Bantad, in Ghost lab there are these two doctors that are appassionated to paranormal stuff,  in Project S shoot! i love you there are all the main who loves archery, i told you all of the dramas that i remember with the thing you asked, hope it will help ^^

Here are some where the male lead is a comedic geeky/nerdy/dorky
