After winning first place in Show Me KPOP survival audition, Kim So Jung was given the golden opportunity to sign a double contract with top 2 entertainment agencies SM and YG. However, the catch is that she will only be allowed one month in each SM and YG, and has to decide which agency she wants to debut in by the end of the two months.

Choi Jae Hyun, So Jung's classmate and a chaebol, is in a one-sided relationship with her. He follows her into the entertainment industry and joins YG Entertainment by pulling some strings with high-up artist G-Dragon. Having made an acquaintance with GD when they met in a party, he asks for a favour: to be accepted to train in YG.

Meanwhile, So Jung meets the SM boy-band members of Super Junior, Shinee and EXO, whom she has only ever seen on tv. She finds herself continuously bumping bad boy Baekhyun and troublemaker Tao.
