At the age of twenty-eight, Kim Jisoo, who had already experienced the pain of loss and betrayal, closed her heart, choosing life "one day". But everything changes when, by the will of fate and work, she meets Jennie - the most famous, young and titled star of Hollywood.
That's just the superpopularity of a megastar, fiercely guarding her life from people, is not the only problem for unexpectedly flared feelings. In the past, Jennie has a more terrible mystery hidden and it returns at the most inopportune moment.
Jisoo met her when she was 13 yrs.old. Both of them were total opposites. Jennie is everyone's favorite and the typical Ms.Popular while Jisoo is the outcast and the awkward lone wolf of the class.
