No joke, Captain Obvious. Never did I infer that all Asians have Korean cosmetics or are Koreans, sounds like a very wild mischaracterization.
I asked if you don't have Korean cosmetics, so, I wonder why you make it about the other Asians when the question was for you. If you don't have Korean cosmetics, you can just say so next time, it was a simple yes/no question.
And the cosmetics are a well known meme/reference whenever joking around Eastern youthfulness, since Korean pharmacology is well praised in this area. You either get the reference or not.
And the meme mostly regained pop. with that young looking Singaporean dude. It is meme culture. Kay? It's not supposed to be argumentative like you make it sound by bringing up more generalizations to atone one generalization. It does not apply only to Koreans, but to other Asian descents 'cause ethnicity is more recognizable than nationality. It is clearly a stereotype, which does not need introduction and which happens to fit the bill with this MC specifically. Bye.
mc looks like a teenage boy im sorry
