I feel like the manager is just the super polite type who's very good at his job so he's nice to everyone and very agreeable. But I totally understand why she blushes from all of his kindness.
I'm sure a few of Hoojoon's fans like him for who he really is.
In real life, I like how some idols are allowed to be weird haha. Its sad how some still have to have a perfect image. But a lot of the big companies allow some of their idols to have personalities to a certain extent. So I really like reality shows and other segments that are chill or challenging. Sometimes there are fun moments where they forget or almost forget about the cameras.
