Look around you, and I’m sure you’ll find at least one person who is either into Korean pop music (K-pop) or Korean dramas (K-dramas). The popularity of Korean cultural products, be it music, TV shows, fashion or skincare, is called the Hallyu (Chinese term for the word Korean) wave. Hallyu wave’s acclaim has had a positive impact on the South Korean economy, with boy band BTS contributing US$3.6 billion to the country’s economy all by themselves.
