I mean, you can know another language but not be fluent. Also they spoke rapidly at the same time. Meanwhile Jaekyung only spoke a few words and he spoke them slower since ya know he wants to sound more menacing. This is literally my own experience. Any language you're trying to learn that has the native speakers could all be auctioneers is hard until you get more experience.
The delulu transcends all languages I guess. Seriously though you can't tell me that you can selectively understand another language. Dan I genuinely can't tell if you're a genius or dumb.
