Chinese American Alice Choi is literally living the dream: she was discovered singing karaoke in Seoul and been assigned to a five-person group that is set to debut in a few months time. She's told catching up to her bandmates will be hard work, but she doesn't grok the emotional component of that labor. Like most K-pop trainees, Alice, renamed "Harmony" by her label, must be perfect. The first step to perfection is making weight, so while she's learning intricate dance moves and trying to fit in with her roommates and navigate the loneliness of having little contact with the outside world, she's on a cabbage diet.

It's a K-pop novel, so expect forbidden romance, competition between trainees, struggle to achieve, and family not understanding the pressure.
