A personality like got7's Jackson

The main characteristic I love is talent. I don't care how pretty they are if they can't sing or dance worth anything. I hate when I hear some singers struggle so much with either high note or rapping sequences, if you know you can't do them stick to what you can do (sadly most of the time is not their choice).
Another thing I look for in idols is kindness, it's their job to make people think they're as close to perfect as possible but kindness is so easy to spot and for me it's very attractive.
Other than these two any other positive trait is just a bonus for me :)

Those who are good at what they do (Singing, dancing, rapping, etc..) and love it. Humble. Knows how to behave on camera--entertaining, well-spoken, just charming however they do (As in, however they manage to be charming. Being charming constantly is not a requirement.). Possesses visible integrity. And after one has fulfilled all of that, any further unique traits (Funny, playful, distant, proper, etc..) would just complete their individual character, already established as basically charming and probably worthy of being idolized.

y, outspoken, cold, a LITTLE humble yet always takes care of the image (Turn OFF) Just kidding :D HAHA.

Those cute and playful ones.
Dork, Weird, outgoing, extrovert, but yet they are still interesting. :D
