Amber is a trainee from Los Angelos California. She hadn't even expected she would get a chance to audition, let alone be signed to the SM Label, but here she was and she was going to try her best. She never suspected how hard it would be though, making friends, learning the language, standing out as pretty much the only tomboy in a land where there is a clear divide between what is strictly female and masculine. She's got a few friends who were originally from America, Canada, or China, but other than them, she's pretty much an outcast. And people aren't afraid to let her know it. 

Krystal Jung has an aura about her. A cold one. People find her hard to approach, plus her sister has already debuted. In a land of trainees, that puts her on a different level. To them she is a cold, stuck up, Princess who is guaranteed a debut while they have to struggle from the very bottom, not knowing or caring that she is doing the same. In SM, nothing is a guarantee. Certainly not a debut, and especially when it's hard to find another bundle of trainees you get along with. So Krystal fears she will only have her sister and a few select friends to hang out with until one day she bumps into the mysterious Amber Liu.
