Like many others are feeling right now, I am rather disappointed in her behaviour towards this individual. However, I am not disappointed by the 'revelation' that she isn't a god-like figure, that doesn't have any flaws.
Shouldn't we all know by now, that idols aren't the flawless people that we wish they were?
Whatever went down that day is between the two parties involved, and the severity shouldn't be up for speculation. Likewise, anything that hasn't been officially confirmed (regarding supposed other staff, and even speculating how she treats her members?), shouldn't be used towards condemning her.
Condemn her for her behaviour towards this stylist. However, don't paint Irene in a way that none of us (as k-pop fans) know....
I truly hope that she does reflect on this, and I also hope that it's a rare incident. As this stylist and many more staff have praised Irene's attitude in the past.
But regardless of what has happened. I will continue supporting her and Red Velvet, because I don't expect them to be flawless, and I accept that they (like you and I) can have their moments....
That's all I have to say on the matter, though. And I hope that others won't make speculations on matters that haven't been officially confirmed by all parties involved.
