Jung-In Byun

Jung-In is the president of music company JI Entertainment producing a music drama. Jung-In was born into a wealthy family and has never lacked money. Jung-In is also good looking and has good manners. Because of this, Jung-In appears to be highly eligible bachelor for marriage. But, Jung-In also has a cold side - he doesn't like becoming too close to people. His weakest point is that he can never say no to his father. He enters into a 100 day fake marriage with Mary and soon falls in love with Mary. Jung-In also comes across Mu-Gyul who will help fulfill Jung-In's dream in the music world. Mu-Gyul will also become a rival for Jung-In over Marry. Then Seo-Jun enters the picture.
