This thread. If you& #39;ve watched reply 1988, the hair of the ajummas was a symbol for that era. It was not directed to offend a particular race and they stated it directly on the subs who hyunjin is portraying. https://twitter.com/cherrywooo/status/1278386946880897024">https://twitter.com/cherrywoo...
I& #39;m sure that the character he portrayed was based off of that era since the cartoon was ages ago.
I just hope mnet did not make that as a thumbnail since it can be easily misunderstood without a visual representation of who he was portraying.
