I don't know 99% of the artists they're talking about, but since this place has some kpop fans I figured I'd link you guys to this youtube channel if you haven't seen them before. They review and talk about kpop and they're the most adorable couple I've ever seen.
Well, that's to a specific video, but you can watch it to get a preview of what they do. And sorry if you guys already know of them haha. I always get their videos on my recommendations so I watched a few and I thought they were cute even though I know squat about kpop.
