It is even more absurd to ask questions only in English, Brazilian Portuguese, French, German, Italian or Spanish so that 'everyone can understand'.
I re-posted the question in English, but it still doesn't make sense.
Korean is also one of the international languages and is widely used in international organizations and events. K-pop songs with Korean lyrics are also widely sung around the world.
So why does King ignore Korea so much?
Why on earth do you provide a Korean service?
On the other hand, how would you feel if you were asked to communicate only in Korean, Chinese or Japanese so that 'everyone can understand'?
If you don't know Korean, you can just use Google Translate. It's not difficult and is a good method.
