Q. What are some things an idol does and doesn't need?
Necessary... Energy / Miniskirts
Unnecessary... Negative feelings
Something needed is a strong heart!! Since you're in a position of having to give everyone energy!!
Not needed are complaints!! If you toss around complaints, you'll look unconfident!!
Something needed is of course a smile! If I don't smile, I don't think the fans will smile either.
As for not needed, gorillas......? lol
Necessary... Being yourself
Unnecessary... Shyness
Something needed is... a smile
Unneeded is... a serious look
Something necessary → Being positive
Unnecessary → Being negative
