I agree with what most everyone has said, I don't think any of them are so-called "faking it." Even though the K-Pop industry (or Korean entertainment industry in general) could be described as shallow or superficial, I think that many members of groups make a genuine connection to each other. They're usually living, sleeping, and eating together and face whatever obstacles together so you'd think they'd have to learn to get along because each other are all they've got.
