First of all, I appreciate this engagement. In terms of the need for sanitised media, I don't think anyone believes international audiences solely drive it. Its mere existence before international audiences were privy to kdramas is evidence of that. However, the byproduct of consuming such media has led to the adoption and subsequent maintenance of this demand.
There is a gap in the market for this type of media, which is why it has gained popularity over the years. However, my point is more that the industry cannot merely become an outlet for international fans' desires.
Although you can say that Western audiences are trying not to impose their cultural expectations, they are imposing a whole new set of expectations, which could be argued are even more insidious and dehumanising. The expectation is no longer about norms specific to a culture, good or bad, but instead a curated fantasy. "I am consuming you, so you must be perfect."
I mentioned that media could be used for escapism and wasn't necessarily trying to criticise that side of kdramas because that type of content has its place. However, all K-media can't be expected to reflect that alone, and the producers and writers shouldn't feel pressured to conform. Media is diverse, and to say that only the West should produce A24-style material, whatever that means, is to infantilise the industry.
Overall, the point isn’t that every drama needs to be political out of fear of fetishisation or that audiences must engage with kdramas outside of the romance genre. The issue is that, whether this expectation comes from domestic or international audiences when foreign audiences specifically require perfection in romantic characters all the time, it can only be rooted in fetishisation. They ultimately strip an entire group of people, reducing them to mere objects of consumption.
If these characters were viewed as part of a piece of media or art, deviations from this fantasy wouldn't ignite annoyance because one would recognise that these portrayals are also valid. Similarly, just as most of us would find it reductive if African cinema were expected to solely focus on war and conflict, kdramas should not be confined.
