That's his job though, that's how pop star idol in asia work most of the time. The fans there are literally everything the agency care about since they give them money, give no fck to the idols.
I know it is, but he's still a prick xD You can do your job well and be a dick at the same time xD
But seriously tho, it's horrible. I've never got the whole idol business in Asia, just hearing about rabbit fans is enough for me to back away. I'm surprised there are still people willing to do that job, if everything about not even being treated as a human being is true. It sounds like a nightmare job.
Some do it for the fame, some for the money, some because they wanted to do it and they have a talent for it and want to pursue their dream. There are like a lot of fan girls/boys that don't want their favorite singer to be dating anyone since they wanted them all to themselves lol. In Japan the fans are actually less toxic and addictive to the idols than Korea and China since the people there have a really high moral. In japan you don't have to take any kind of quiz o test until grade 4 since Japanese want to focus on teaching young children moral and ethics on how to be a good person in the society is more important than grades.
You got me for a second there #－.－)
Btw, manager can get fucked. I know he's just doing his job, but he's a prick.
