Cos they can't sing for shite sis, lol. Every vocalist they hype up is dogshit when you remove all the processing and mixing and live autotune. Kpop is literally using men who act like teenage virgins and women who are willing to look and act as pure pedo bait in order to create a fan base where awkward, anti-social people who can't otherwise function in society are able to use the parasocial relationship to pressure these idols into molding their career and personality exactly according to their 'fans', to live vicariously through them. It isn't about anything else haha. And it's not a genre that is respected in the slightest in SK. It's only now that BTS are so lionised and have become somewhat bigger than the industry itself, that it's now seen as a somewhat popular thing for kids to do.
