Kim Hye Jin grew up confident and cherished, but her life changed after her family lost its wealth and her appearance shifted during her teens. As an adult, she works part time and lives with a friend while searching for stability. One day, her childhood friend Sung Joon contacts her to reconnect. He remembers her as the pretty girl who once comforted him, but he does not know that their roles have reversed and that she now looks very different from her younger self.
Afraid to disappoint him, Hye Jin asks her close friend Min Ha Ri to pretend to be her for the meeting. The plan seems simple until Hye Jin secures a job at a fashion magazine and discovers that Sung Joon is her new boss. He treats her coldly at work, unaware of who she actually is or how they once supported each other.
As Hye Jin struggles to hide her identity, unexpected complications arise, including growing attention from her coworker Shin Hyeok. Her journey becomes a mix of personal growth, tangled secrets, and the challenge of facing the person she once knew while trying to rebuild her confidence and her life.
