Some of the just have that attitude that you know will get them into trouble some day.
Right now I am thinking that about Yunjin. It is written all over her, like she's a Korean-American, LA girl, these ones always get into trouble. They ain't fit for the conservative society of Korea, one day they just crack. Aaron was like counting his days at Nu'est, he couldn't take it anymore. Jae got into trouble the second he left Day6, Ailee, Gna, Jessica, Amber, Jay Park. That's literally all of them with a few exceptions.
