BeMyLover's manga / #horror(2)

I enjoyed Black Mirror and definitely found it a bit disturbing but I feel like I'm not following the mirror aspect. So is it saying that it's not just Yeon and Jun being connected but other people as well? Like there's the hidden/disturbing secret world where people have these alter forms for their darkest desires? It's cool idea but I don't know, maybe I would have liked it had it only been just these two instead of the world. In a small way takes away from their pain. Also thank you God Hyunjoo and her sister didn't come. That would've sucked. Also wanted the coach to be meaner in the end. Would have made his death more compelling but overall I enjoyed it
