@chucke1992 It is how the idol industry works. Also majority of the money from the merch doesn't go directly to the idols but to their manager, event organizers, their agency, etc.
@Kampfarsch You need to understand what "addiction" is. You know that it is bad but you can't give up it. I myself understand it as I am addicted to gaming. Every time I told myself to just play for one hour then go to sleep, I ended up playing to dawn.
Also sex addiction is even harder to quit. You said " isnt that hard" means that you don't understand about sex addiction. How do you think men keep going to brothels and women keep coming back to host clubs even if they are broke and in debt?
