Is this a thing? I hope the author is careful with that though because I heard alot of Koreans are straight up racist to Filipinos.
The recent chapter confirms it. His cousin knows Filipino Martial Arts and is just hiding it.
Yes South Koreans have negative racial stereotyping on Filipinos, these are also the result of Poverty Porn Media and the common encounters of South Koreans with Filipinos as Domestic Helpers, Bar Entertainers, Janitors, Factory Workers, and Minimum Wage English Teachers with Accents.
Despite the negativity Filipinos would still be attracted to their media and Webtoons.
Definitely his Cousin took cues from the Philippine Government to run a prison. I suspect he might know Filipino Martial Arts too.
