The teenagers who get into KPop fandom somehow end up watching KDramas, especially romances that are usually made for lonely housewives who're probably frustrated with their husband or their sex life. One common subgenre is the "Noona Romance", Noona is Korea's Onee-san in which the female lead is years older than the male lead. Electric jew is manipulating their emotions. It might be different across the world but South Korea seems to celebrate older women relationships.
