Still This isn't even a big deal. As a Korean man myself. I see this often asked by those of the older generation, for a variety of reasons. Some mannerisms that forgieners display make it seem like they aren't paying attention so you might ask halfway through the conversation " are you following me? Or do you understand". Another reason could be they aren't familiar with your level of Korean and may ask a few times during a conversation especially if the subject presented goes into more formal speech a different dialect or newer slang a good amount of that stuff isn't taught in a school curriculum. The older generation is abit more rough with it like "do you understand Korean" instead of" are you understanding me well?" One sounds less harsh both mean the same fucking thing neither is done to mock you.
Thank you for proving insight into Korean culture. I was explaining how since most of the hate is from us international fans we don't care about the chart question. Our concern was with how we perceived how he seemed when he kept asking Tzuyu if she understood Korean.
We are not Korean so to us it seemed rude. Do I agree with ONCE sending him death threats? Of course not! We just were not aware of the language behind it, only with what we knew of subtitles and those translating made it seem like he was badgering/looking down on Tzuyu's Korean rather than checking to see if she was understanding of the question.
