Imitation

Three years before the main events of the story, idol trainee Lee Ma-ha's dream of debuting in a girl group is cut short when news of a fellow trainee Annie who had committed suicide breaks out and disturbs the K-pop industry. Elsewhere, the comeback of popular boy group Shax kicks off with a rough start as Kwon Ryok is forced to cover for a co-member Lee Eun-jo who suddenly goes missing. At the present time, Ma-ha struggles to support herself by impersonating the famous solo artist La Ri-ma while Shax has become the most popular group in the industry, with Ryok developing a successful acting career.

After an eventful movie shoot, Ma-ha chooses to quit pursuing idol stardom and start a new life, a decision seconded by her teammates Yu Ri-ah and Shim Hyun-ji. In a press conference, reporter Byun Jung-hee causes a stir by questioning Shax about Eun-jo whose disappearance has already caused an emotional toll on Ryok. Meanwhile, Shax's ex-manager Ji Hak returns to the K-pop industry and decides to manage Ma-ha, Ri-ah and Hyun-ji. The trio changes their minds, resolves to accept Ji Hak's offer and adopts the group name "Tea Party." Ji Hak starts implementing his unorthodox way in managing an idol group.

Controversy is stirred amongst Shax fans when Ma-ha is photographed returning Ryok's jacket to him after a television shoot. Ryok is forced to apologize to fans, who brazenly demand Shax avoid Ri-ma and Ma-ha at all costs. In a meeting with her CEO, Ri-ma threatens to end her contract if she does not get to record a duet with Ryok. Meanwhile, Tea Party work to find their perfect debut single as Ji Hak prepares for their first appearance on a music show. Elsewhere, Ma-ha's best friend Lee Yu-jin prepares a comeback with his own group, Sparkling, but he is troubled by Ma-ha's interactions with Ryok.
