that's not what they meant, they're saying that there are negative comments and all of them have been deleted and the one that is left is the positive one only, like lol, it's just that-
the ending is really scary- like imagine someone u don't like or do a bad things to u etc ended up being with u everywhere where u can't control it, i would be terrified, i hope sewon gets to find a way to get dr myung out of his sight / can't see him anymore
