This video is proof of the sexual moral degradation that is happening in South Korea. See how WAVEYA devolve from YouTubers into internet sluts.
Asian Moral Degradation has been happening for decades, and is a cultural phenomenon not yet well understood. Most accepted is that Asian women are genetically built to better become cockdrunk, and with increasing living standards this happens at an increasing pace, though other ideas exist.
Ari and MiU from WAVEYA Dance Group both characterize this well, as they started out over a decade ago as YouTubers, mainly doing k-pop dance covers. However, as fame overtook them, the easy money, coupled with the genetic built in arousal they get from exposing themselves, led to an increasing dive into being internet sluts.
