Sometimes these KPop idols deserve criticism of what they have done. This might sound harsh but its what the idols have signed up for. Some of them having Cafe and restaurant although it is not taken care directly by the artist but by his family but theres nothing wrong visiting here.
But groups like BTS have proven that an all-Korean group can make it big without foreign members.
Male idols born in 1992 will all be entering the military this year and some have already joined such as Winners Lee Seung-hoon and Kim Jin-woo a 91-liner born in 1991. This is as opposed to say a boy group singing about love and being in a relationship when very few kpop idols have had any serious relationships. K-Pop comes from South Korea and South Korea is a country that has difficulty tolerating individualism and anything that is different from what is already established. I cant think of a single Chinese kpop idol who decided to stay with their Korean Company after their initial contract was over if they even made it that far.
