I am fascinated that some fans expect idols to always smile and be cheerful and always interact and be balls of sunshine, when that’s something impossible. Sure, they have chosen to be in front of public all the time, but never the less idols are humans and they have their bad days and grumpy moods and deep thoughts just like any other person and they are allowed to show them. Personally I prefer seeing my bias thoughtful/serious/grumpy rather than him pressing down what he feels to force out a fake smile to please the crowd. When he shows his true emotions I am less concerned than when he smiles and one can see it’s not sincere. Nothing hurts more than smile that is not sincere.
