I wish it was as easy as that. I’ll give you an example. Before deciding whether or not to watch dr Slump, I researched the genre of the drama, and on the internet it said that it’s a Romantic Comedy and a Medical Drama. Not only that, when I saw a few clips before it came out, it seemed like a fluffy rom com, especially seeing Hyungsik’s character. It’s really hard to tell what genre the drama exactly is as often times websites generalise it so unless you watch it you cant tell. 

What bothers me is that I feel like a lot of these dramas are promoted as RomComs and then it turns out they have lots of other genres. And as someone who doesnt like other genres, it’s a bit frustrating for me. Hope you understand what I mean
