(based on the song MAMA and history) Jay, (Kim Ji-Jae) is the heir to the SM Group, which included the entertainment branch of the group, S.M. Entertainment. After graduating she decides to audition for fun at her company, however because of her talents she is actually accepted, but then she meets the k-pop group Exo and things she thought were 'possible or impossible' are proven wrong. What happened to the laws of physics that she learned at Harvard? Or her strong beliefs that there is no such thing as the supernatural?

A cold girl outside but sweet and delicate inside. She has the goddess figure and face, even a brain like Athena and too rich family, Lee Minka. Meeting the noisy but cute and handsome EXO boys. Will her peaceful life be more adventurous with them?
