I seriously think that every fan of kpop or kdrama or anything like this should watch this documentary because it starts to show how the person who's there (it can be an idol or an actor, it doesn't matter) is treated inside the companies and how they have to deal with all kinds of pressure just to follow their dreams. I watched it long ago but I still remember of how shoking was all of that information.
This simply shows how humans they are. They're not perfect. They have to deal with people being rude all the time, family pressure, irresponsability of others. God damn it, Hyemi was afraid of telling their manager that she was sick.
What i want to say here is that these people already had to take a lot. All we as fans should do is suppot them and stop being mean to one or another just because of idiot reasons.
