Go Joo-yeon, een egocentrische steractrice, heeft altijd gekregen wat ze wou. Roem, geld en knappe jonge vriendjes. Nu ze in de 40 is en haar acteercarrière bergafwaarts gaat, vraagt ze zich af of ze zich moet vestigen met haar geheime vriend die 12 jaar jonger is dan zij. De vriend is echter alleen geïnteresseerd in het benutten van haar roem en bedriegt haar achter haar rug.
