I think it's important to sometimes acknowledge one of the big reasons we are all into k-pop: visuals.
Maybe this question is in poor taste but who do you personally think is the most attractive/beautiful/handsome idol ever?? Obviously this is all subjective and just for fun, don't be rude.
Little did I know, the first idol I ever saw would remain my #1. Since the day I laid eyes on her, my answer has been Ms Jennie Kim. She is the standard against which I judge all other idols, and she has yet to be topped in my eyes.
If I had to choose a guy, it'd be Jungkook. I ain't gay, but that dude is hot.
