"i need some pure comedy dramas, without romance. but its okay if its thiller, horror or any genres. "
By definition, if it includes other genres, it's not "PURE" comedy. Many of the Dramas that you list are not even primarily comedy, like Psychopath Diary and Vincenzo. Since both of them are built primarily around murder and crime, which aren't remotely comic (I can't think of anything less comedic than a psychpoathic serial killer) , I'm going to encourage you to consider a couple of Dramas that are heavily comic, even though they feature romance.
Humour is VERY personal, and what one person finds funny another hates - I'd rather pull out my own teeth than watch Eulalala Waikiki for example. That said, here are two Dramas in which I literally laughed out loud more often than in any other of the more than 400 Dramas I've finished
